Investigations of Linear and Nonlinear Optical Properties of Transparent ZnO Thin Films Grown by Sol-Gel Method


The optical properties of ZnO thin films grown by sol-gel method were studied using second and third harmonic generation and photoluminescence measurements, respectively. The structural properties of the ZnO thin films were carried out using x-ray method. The effects of the thickness variation and annealing temperature on the crystallinity parameters were observed.
