The Influence of annealing temperature on Structural and Optical Properties for thin ZnO Films Prepared by pulse laser deposition

Abstract

In this work, structural and optical properties for thin ZnO films prepared by pulse laser deposition technique, on glass substrates, have been studied as a function of annealing temperature. This study shows that the films have energy gap decreases from 3.26 eV to 3.14 with increasing Ta from RT to 673 K.
