| Abstract: | CdS nanoparticles stabilized with sodium hexametaphosphate were prepared. Colloids with different sizes of CdS nanoparticles were obtained by controlling the concentration and chemical ratio of the reactants. The morphology of the CdS nanoparticles was observed via ultra high resolution TEM.The influence of quantum size effect, surface state and impurity to the photo-emission of the nanoparticles were investigated according to the absorption spectra and fluorescence spectra. |

| Keywords: | cadmium sulfide nanoparticle colloid UV-vis absorption spectrum fluorescence spectrum |
