Structural, Electrical and Optical Studies of NixCd1-xS (x = 0.8, 0.6, 0.4 and 0.2) Nanoparticle System

Abstract

This paper demonstrates the synthesis of NixCd1-xS (x=0.8,0.6,0.4,0.2) nanoparticles by microwave-assisted chemical precipitation method. The prepared samples were characterized by XRD, EDAX, SEM, UV-VIS, and PL spectroscopy. The energy-dispersive x-ray analysis confirms the existence of Nickel, Cadmium and Sulphur in proper ratios. The DC electrical resistances were measured in the temperature range of 300 K-500 K. The temperature resistance curves of all the samples show phase transitions above a particular temperature. The UV and PL spectra of all the samples were compared and studied.
