PREPARATION AND CHARACTERIZATION OF Cu DOPED NiO NANOPARTICLES: EFFECT OF pH

Abstract-In this paper we discussed a facile chemical co-precipitation method for preparing water soluble Cu doped NiO nanoparticles and studied the pH influence on the structural, morphological, compositional and photo luminescence properties using X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive analysis of X-rays (EDAX) and PL Fluorimeter. Broadened XRD peaks confirmed the formation of nanosized NiO: Cu nanoparticles with face centered cubic (FCC) structure at different pH values. SEM and EDAX analysis shows surface morphology and effective elemental composition of prepared nanoparticles. PL peaks of Cu doped NiO nanoparticles at different pH values ware observed around 434 nm and an increase in PL intensity was observed with increase in pH value.
