Preparation and Characterization of Pure and Lanthanum Doped ZnO Nanoparticles by Solution Route

Abstract

In this study, Undoped and lanthanum doped ZnO nanopowders have been successfully synthesized by solution method using the mixture of Zinc acetate dihydrate and ethanol. The powders were annealed at various temperatures. The effect of lanthanum incorporation on the structural and optical properties of the ZnO nanoparticles has been investigated and the effect of temperature impact on as-prepared ZnO nanoparticles with respect to the morphological and optical characteristics has also been investigated. Structural studies were done by using X-ray Diffraction (XRD). Morphological studies were done by using Scanning Electron Microscope (SEM) and Atomic Force Microscope (AFM). The surface-related optical properties have been investigated by Raman spectrum.
