TL;DR: The photoluminescence intensity of ZnS-AgInS(2) solid solution nanoparticles was remarkably enhanced by increasing the heating temperature to 180 degrees C, above which the emission was simply diminished, while ZNS coating of the particles resulted in further enhancement of PL intensity, giving the highest quantum yield.

Photocatalytic syntheses of azoxybenzene by visible light irradiation of silica-coated cadmium sulfide nanocomposites.
TL;DR: Photoirradiation of a deaerated 2-propanol aqueous solution containing nitrobenzenes and rhodium-loaded silica-coated cadmium sulfide nanoparticles produced azoxybenzene with relatively high selectivity, the photocatalytic activity being enhanced with a decrease in the size of the semiconductor particle core.

Nanosize-Controlled Syntheses of Indium Metal Particles and Hollow Indium Oxide Particles via the Sputter Deposition Technique in Ionic Liquids
Toshimasa Suzuki,Ken-ichi Okazaki,Shushi Suzuki,Tamaki Shibayama,Susumu Kuwabata,Tsukasa Torimoto +5 more
TL;DR: In this article, the size of the hollow particles was slightly larger than that of the In/In2O3 core/shell particles used as a starting material, whereas the void space formed inside hollow particles were smaller than the corresponding In metal cores.

Stacked-structure-dependent photoelectrochemical properties of CdS nanoparticle/layered double hydroxide (LDH) nanosheet multilayer films prepared by layer-by-layer accumulation.
TL;DR: Inorganic multilayer films prepared by layer-by-layer accumulation of positively charged layered double hydroxide (LDH) nanosheets and negatively charged CdS nanoparticles of different sizes exhibited characteristic photoluminescence spectra indicating the efficient energy transfer of photogenerated excitons from nanoparticle layers of smaller CdCdS particles to those of larger ones.

Photosensitization of ZnO rod electrodes with AgInS2nanoparticles and ZnS-AgInS2solid solution nanoparticles for solar cell applications
TL;DR: In this paper, ZnS-AgInS2 solid solution (ZAIS) was successfully immobilized on the surface of ZnO nanorod electrodes without using additional cross-linking agents.
