Abstract
Zinc oxide (ZnO) thin film is a transparent conducting oxide thin film and has attracted significant attention because of its potential applications in optoelectronic, solar cells and heat mirrors. The ZnO thin films were deposited by spray pyrolysis method. The films were grown on glass substrates at 415, 445, 475 and 505 oC substrate temperatures. The transmittance in the visible region and energy band gap values range from 79% to 85% and 3.32 to 3.34eV respectively. Raman spectroscopic analysis indicates that there are two peaks at 436 and 556 cm-1. It was concluded that ZnO thin films with optimal growth conditions using spray pyrolysis is an excellent material for transparent conducting oxide films.
