Study of ZnS: Ni Cu NPs for Opto-Electronic & Spintronic Applications

Among the II-VI semiconductors ZnS shows various luminescence properties such as photoluminescence electroluminescence mechanoluminescence and thermoluminescence which enable it to be used in the fields of optical displays. ZnS doped with transition metals and rare earths exhibits attractive light-emitting properties with increased optically active sites for novel diverse applications including light-emitting diodes (LEDs) sensors lasers electroluminescence flat panel displays infrared windows and bio devices besides spintronic applications.PVP capped pure Ni doped and Ni & Cu co-doped ZnS nanoparticles were synthesized using chemical co-precipitation method at room temprature and systematically characterized the material using structural morphological optical magnetic and electrical studies.
