INVESTIGATIONS ON STRUCTURAL, DIELECTRIC AND OPTICAL PROPERTIES OF Cu- DOPED ZnO NANOPARTICLES.

The structural, morphological, optical and electrical studies of Cu doped Zinc Oxide (ZnO) nanoparticles which were synthesized by hydrothermal method. The PXRD results confirmed that the synthesized material is polycrystalline ZnO and the average crystallite size of the Cu doped ZnO were determined by using the Scherrer’s formula. Various functional groups were analyzed by using the FTIR analysis. Surface morphological and chemical compositions were analyzed using SEM and EDX. The optical properties were carried out using transmission and Photoluminescence spectrum. The dielectric properties of the Cu doped ZnO nanoparticles dielectric constant, dielectric loss, AC conductivity were analyzed in various frequencies and temperatures at specific conditions
