Synthesis and Characterization of Zinc Oxide and Aluminum Doped Zinc Oxide by Sol-Gel Method (Only Abstract)

Abstract

In the present Investigation we have used sol-gel and spin coating method to synthesize zinc oxide Nano particles having modified parameters with a comprehensive overview of their structural and experimental study. To evaluate its electrical, structural and optical properties as synthesized particles were analyzed by X-Ray Diffraction (XRD), UV spectroscopy and Particle size analysis. These crystalline size nano particles were utilized in sensors to detect volatile organic compound (Ethanol, Methanol and Formaldehyde) and was found to have high sensitivity and quick response time. In this paper we increase the overall band gap with the increase in concentration of aluminum and at the same time electrical conductivity of ZnO is also changed with the concentration of aluminum.
