Structural and Optical Performance of The doped ZnO Nano-thin Films by (CSP)

Abstract

Abstract In this study, were investigated structural, optical properties and morphological ofZnO and Te-doped ZnO Nano-thin films deposited by Chemical spray pyrolysis(CSP) method. The structural properties of films were studied as pure and Te dopant ZnO at concentration 2 and 4%. The films were characterized by XRD to study the structure of films. It was observed that the hexagonal wurtzite structure of ZnO for all samples. The films exhibited wurtzite (102) preferential growth in pure and the dopant ratios. Grain size values calculated fromScherrer’s formula of the films were varied in range of (79-113) nm. The band gap energy values were calculated respectively for undoped ZnO and 2% 4% Te doped ZnO samples.
