Researchers are working on extensive use of different oxide materials thin films from last few decades. In this review article, different deposition methods of preparation of ZnO thin films by various researchers are studied. Out of which, Sol gel method is found most suitable, simple, low cost method, hence studied and explained here in detail. During the last years, ZnO thin films have been studied extensively due to their potential applications in applications as optoelectronic devices or photovoltaic cells, gas sensing device, humidity sensing device, piezoelectric transducers, optical waveguides, acousto-optic media, surface acoustic wave devices, transparent conductive electrodes, solar cell windows, varistors etc. Effect of doping on physical properties of ZnO and their use in different sensing applications are studied and mentioned here.

Thin film, ZnO, Sol gel method, sensing applications, dopants etc.
