Synthesis of photoluminescent pure and doped cadmium sulfide by reverse microemulsion method

Nanomaterials with controlled morphology have drawn significant attention due to their unique optical, electrical and chemical properties originating from their quantum size. The reverse microemulsion method is one of the most recognized soft chemistry routes for the synthesis of nanocrystals with very narrow size distribution. We report on the synthesis of photoluminescent cadmium sulfide nanoparticles doped with different ions (Ag⁺, Mn²⁺, Zn²⁺) by reverse microemulsion method. The structure and morphology of the samples were investigated by X-ray diffraction, scanning and transmission electron microscopy. The optical characterization of colloidal systems was carried out by UV-vis and photoluminescence (PL) spectroscopy. Different photoluminescent properties were obtained by varying the doping ion and its content.
