“…The significance of the ZnO films is such that various techniques have been employed to obtain it, such as RF magnetron sputtering at various temperatures [1], thermal oxidation of Zn ion beam sputtered films [2] Zn-vapor release in argon atmosphere and subsequent oxidation in air [3], vapordeposition method (PVD) [4], chemical vapor deposition (CVD) [5], etc. It has also been reported the synthesis of nanoparticles of ZnO in aqueous medium under microwave irradiation conditions, deposited on different substrates from zinc salts and various solvents [6].…”
