The results reveal strong differences between dynamics of terbium-related photoluminescence in thiosalicylic complex and CdS nanocrystals. Our interpretation is based on the capping acid binding modes towards terbium and cadmium ions on the CdS nanocrystals surface 关键词: cadmium compounds;II-VI semiconductors;nanoparticles;optical properties;organic compounds;photoluminescence;semiconductor doping;terbium;visible spectra;optical properties;terbium-doped thiosalicylic-capped CdS nanocrystals;optical spectroscopy;terbium-related photoluminescence dynamics;CdS nanocrystal dynamics;capping acid binding modes;terbium ion;cadmium ion;CdS nanocrystal surface;visible spectra;CdS:Tb
