Studies on the Synthesis and Characterization of Nano Phosphors for Field Emission Devices

H. L. Vishwakarma, Archana Sharan, Anju Singh

Nano phosphors were synthesized by chemical precipitation method with mercaptoethanol as the capping agent. Manganese doped ZnS nano phosphors (ZnS: Mn) with varying concentration of capping agent as well as of Mn2+ were synthesized at room temperature. The optical absorption studies show that the absorption edge shifts towards blue region as the capping agent concentration is increased indicating that the effective band gap energy increase with decreasing particle size while with the change in doping concentration no variation was observed in the absorption spectra. The nano phosphors obtained were characterized by XRD. It was found that as the capping agent concentration is increased, there is reduction in particle size.
