Paper Abstract

High temperature colloidal doping method has been used to synthesistransition metals (M = Cr, Mn, Co, Ni, Cu) MCdS/ ZnS core/shell nanoparticles. Transition metalsions were incorporated into the CdS quantum dots pursued by 6 mono lyres of the ZnS materials, which was enveloped doped CdS um dots. These doped nanoparticles were further studied using transmission electron microscopy (TEM), time resolved spectroscopy, ultraviolet-visible (UV-VIS) spectroscopy and photoluminescence (PL) spectroscopy measurements. Transition metalsdoped CdS/ZnS nanoparticles confirm the dual-peaks, first peak (sharp emission peak) is due to CdS quantum dot at 435 nm ; second peak (broad emission peak )(510–660 nm) is come from Transition metalions as compared to CdS/ZnS Quantum dots.
