Y and La Doping Effect on Mg0.04Zn0.96O Nanopowders for Sensor Application

Abstract

In this study we report the yttrium and lanthanum doping effect on Mg_0.04Zn_0.96O powders prepared by wet chemical sol-gel route. The structural phase of the prepared powders is identified by X-Ray diffraction and is found that all the powders are in Hexagonal single phase without impurity peak. The microstructure and elemental analysis is done using scanning electron microscopy (SEM) equipped with energy dispersive spectra (EDS). The bonds formed in the all compounds are determined by Fourier Transform Infra Red spectroscopy technique. The structural properties obtained using UV-Visible spectroscopy technique. The doping effect is clearly observed in each technique that is used in this present work. The effect of yttrium and lanthanum doping effect on Mg_0.04Zn_0.96O structure and its optical properties are explained based on the doping of rare earths in general.
