• Fabrication of CuInS<inf>2</inf>/ZnS quantum dot nanocomposite films and investigation of their influence on performance of soda glass-based luminescent solar concentrators

  Yu Imakiire, Yoshiki Iso, Tetsuhiko Isobe

  Journal of Materials Chemistry C (Royal Society of Chemistry)  13 ( 8 ) 4078 - 4088 2025.02

  Research paper (scientific journal), Joint Work, Accepted,  ISSN  20507526

  　View Summary

  The power generation performance of luminescent solar concentrators (LSCs) is decreased by unignorable optical losses including self-absorption of luminescence by the phosphor and optical absorption by the light guide plate. To address the optical loss due to self-absorption, this research focused on the use of core/shell CuInS2 (CIS)/ZnS quantum dots (QDs) with a large Stokes shift. The QDs were dispersed in ethylene-vinyl acetate (EVA) copolymer to fabricate transparent fluorescent nanocomposite films. LSCs were prepared with the nanocomposite films and soda glass plate, a common building material to investigate the effect of optical absorption by the light guide plate on the power generation performance. Synthesized QDs showed yellow emission at 587 nm with a high photoluminescence quantum yield (PLQY) of 61.1%, and their large Stokes shift of 0.82 eV reduced self-absorption, making them suitable for LSC applications. We evaluated the effects of QD concentration, film thickness, light guide plate material, and film position on the performance of the LSCs. Optimized performance was observed at a QD concentration of 6.2 wt% and film thickness of 324 μm, showing 1.71-fold higher photocurrent and 3.58-fold larger area of incident photon-to-current efficiency spectrum compared to without film. Replacing soda glass with low-absorption white glass increased power generation by fourfold. This reveals the significant absorption losses of the PL and scattered incident light by soda glass. Despite the considerable optical loss, soda glass is a necessary component in a light guide plate to promote the use of LSCs as building materials. Our findings indicate that QDs with a narrow emission peak at ∼520 nm are required to minimize the absorption loss by soda glass.

  　View Summary

  Currently, most carbon dots (CDs) are synthesized from carbon-based materials in autoclaves with high pressure, and then applied in various fields. This work explored the facile synthesis of CDs at atmospheric pressure, which were then purified and embedded in the ethylene-vinyl acetate (EVA) copolymer to form CDs@EVA films and applied in luminescent solar concentrator (LSC) devices. First, crude CDs were synthesized by refluxing p-phenylenediamine (p-PD) in diphenyl ether at 250 °C for 2 h under ambient air conditions, followed by purification using silica gel column chromatography to obtain purified CDs with a photoluminescence (PL) quantum yield of 56% and an average particle size of 15.1 ± 4.4 nm. The CDs@EVA films were fabricated at CD concentrations of 0.05 wt%, 0.10 wt%, and 0.15 wt%, and their thickness was varied from ∼100 μm to ∼500 μm. The yellowish-transparent CDs@EVA films exhibited greenish-yellow emission with absorption peaks at 350 nm and 470 nm, corresponding to the n-π* transition of C=N bonds and the π-π* transition between the highest occupied molecular orbital and the lowest unoccupied molecular orbital of π-conjugated electrons. The PL intensity reached its maximum at 0.05 wt% CD concentration and 408 μm thickness due to self-absorption of emission from CDs. According to the current-voltage curve measurements under AM1.5G simulated sunlight, this film exhibited the maximum short-circuit current (Isc) and power conversion efficiency (η) of the LSC device. Additionally, incident photon-to-current efficiency spectrum measurements revealed that the enhanced Isc and η in CDs@EVA films mainly resulted from emission by absorption through the n-π* and π-π* transitions.

• Photoluminescence enhancement of 1,2,4-triaminobenzene molecules by modification with hydrolytically polycondensed 3-aminopropyltriethoxysilane

  Haowei Tan, Yoshiki Iso, Tetsuhiko Isobe

  Journal of Luminescence (Elsevier)  277   120980 2025.01

  Research paper (scientific journal), Joint Work, Accepted,  ISSN  00222313

  　View Summary

  Small-molecule dyes with longer wavelength and higher photoluminescence quantum yield (PLQY) in water have attracted increasing attention due to their bright potential in fluorescence analysis technologies. Here, a red-emitting fluorescent dye of 1,2,4-triaminobenzene (TriAB) was modified with 3-aminopropyltriethoxysilane (APTES) to avoid contact with water molecules and to suppress fluorescence quenching due to O-H vibrations in water. The formation of a silica-like structure from hydrolytically polycondensed APTES was confirmed by X-ray diffractometry and Fourier-transform infrared absorption spectroscopy. Modification of TriAB with hydrolytically polycondensed APTES induced orange emission in the powder state, although TriAB powder did not exhibit any fluorescence before modification. The PLQY of APTES-modified TriAB in water was 11.1 %, which was higher than that of TriAB in water, 4.5 %. These results confirmed that the APTES derived silica-like matrix shielded TriAB from both water and intermolecular interactions with other TriAB molecules, overcoming fluorescence quenching.

• Implications for applicability of the photodegradation and self-recovery of green-emitting CsPbBr<inf>3</inf> perovskite nanocrystals

  RSC Advances (Royal Society of Chemistry)  14 ( 36 ) 26059 - 26065 2024.08

  Research paper (scientific journal), Joint Work, Accepted

  　View Summary

  CsPbBr3 nanocrystals (NCs) synthesized by the conventional hot-injection method are photochromatic luminescent nanomaterials due to the photoinduced desorption and re-adsorption of the surface ligands. The apparent color and the luminescence intensity were changed significantly during excitation light irradiation and following dark storage; however, the emission wavelength was almost retained. This work investigates the change in emission color of light-emitting diode lighting using the CsPbBr3 NCs to realize photochromatic luminescence. The results showed definite shifts in emission color caused by changes in optical absorption and green luminescence intensity of the NCs, potentially broadening the application feasibility of CsPbBr3 NCs as photochromatic luminescent nanomaterials.

• Open system massive synthesis of narrow-band blue and green fluorescent graphene quantum dots and their application in water sensing

  Journal of Materials Chemistry C (Royal Society of Chemistry)  12 ( 18 ) 6548 - 6558 2024.04

  Research paper (scientific journal), Joint Work, Accepted,  ISSN  20507526

  　View Summary

  Graphene quantum dots (GQDs) are environmentally friendly fluorescent carbon-based nanomaterials. However, there is no report on the massive synthesis of GQDs with narrow-band fluorescence and a high photoluminescence quantum yield (PLQY) using a simple liquid-phase method under atmospheric conditions. In this study, GQDs were successfully synthesized in ∼100% product yield by heating phloroglucinol (PG) with Na3PO4·12H2O in 1,2-pentanediol at 180 °C for 6 h in an open system with air flow, followed by dialysis purification. The high product yield was attributed to the addition of Na3PO4·12H2O as a base catalyst, which promoted the dehydration-condensation reaction between PG molecules. The dispersion of PG derived GQDs (PG-GQDs) in ethanol resulted in blue fluorescence with a full width at half maximum of 32 nm and a PLQY of 54%. Further purification of PG-GQDs by silica gel column chromatography improved the PLQY to 75%. Fourier-transform infrared spectroscopy, 1H nuclear magnetic resonance spectroscopy, and X-ray photoelectron spectroscopy confirmed that dehydration-condensation reactions occurred not only between PGs but also between GQDs and 1,2-pentanediol. The binding of 1,2-pentanediol to the edges of GQDs suppressed the stacking of GQDs and prevented concentration quenching, resulting in a high PLQY. PG-GQDs exhibited negative fluorescence solvatochromism, i.e., the fluorescence wavelength blue-shifted with increasing solvent polarity. Dispersion of PG-GQDs in N-methyl-2-pyrrolidone (MP) resulted in green fluorescence with a PLQY of 96%. Dispersion of PG-GQDs in water resulted in blue fluorescence and a low PLQY of 6% at pH 7, while the PLQY was more than 50% at pH ≥ 11. Using these properties, the sensing of water (pH 13) in MP was investigated. The results showed that as the water content was increased from 0% to 100%, the fluorescence color gradually changed from green to blue and the fluorescence wavelength continuously shifted from 514 nm to 466 nm, indicating their applicability in water sensing.

  　View Summary

  Recently, quantum dots (QDs), which emit light in the band gap and whose emission color can be tuned by controlling particle size through the quantum size effect, have emerged. CdSe, InP, and CsPbBr3 have been developed as QD materials; however, they have problems in terms of toxicity and stability. Against this background, light-emitting materials with high environmental friendliness are required; therefore, we focused on the preparation of luminescent carbon dots (CDs) from abundant carbon sources. In this work, we pioneered an advanced liquid-phase method to synthesize CDs by polymerizing aromatic compound materials in non-aqueous solvents. Furthermore, the effects of surface modification and surrounding environment on the luminescence properties were investigated to control them.

  　View Summary

  An ultraviolet light absorber is used in a photovoltaic module to protect its parts from ultraviolet light. As a result, in photovoltaic modules, the spectral sensitivity of wavelengths below 400 nm is reduced. If a phosphor converting ultraviolet light into visible light is used instead of the ultraviolet light absorber, it is possible to protect the photovoltaic module from ultraviolet light and at the same time to improve the spectral sensitivity of the photovoltaic module in ultraviolet range. In this research, we have developed core / shell type CuInS2/ZnS and CuGaS2/ZnS quantum dot phosphors that convert ultraviolet light to visible light and have high transparency to visible light with high spectral sensitivity of photovoltaic modules. We investigated the improvement of photoelectric conversion efficiency of the photovoltaic module by wavelength conversion of these quantum dots.
