ZNO Thin Film Prepared By Dip Coating Technique for Gas Sensing Application

Abstract

The quantum size effects are commonly expected and simply predict mostly the size will be reduced also causes more atoms are closer to the surface by using ZnO(CH 3 COO) 2. As precursor solution and zinc oxide thin film were prepared by chemical dip coating method. When the transparent and conducting oxides thin films are the component of main devices for solar cells, thin film transistors and Sensors. SEM image and XRD analysis of the films match that all the films are polycrystalline Zinc Oxide in nature were hold hexagonal structure Keywords: Zinc Oxide, Thin Film, Gas sensor I. INTRODUCTION In the last few years the researcher notice that the more carried out on energy conservation and sensor technologies this research involves the eco-friendly semiconductor metal oxide such as TiO 2 ZnO, SnO 2 etc..,(1,2)* Mostly the ZnO can be used to form of powder, thin film substrate. When they hear by challenging application of ZnO thin film having better self -cleaning properties of glass windows.Where theZnO can be coated onto glass and retain their gas sensor and photo catalytic properties.
