Rare Earth Element Doped ZnO Thin Films

In this review, general information has been given about the recent studies on thin film coating techniques, zinc oxide (ZnO) films and doped with rare earth elements (REE). As a method, sol‒gel method is widely used due to its economical nature. However, it seen that magnteron sputter technique also very popular ease of application. Zinc semiconductor wide band gap easy produce supply. addition, does not have negative effects environment human health. All these properties led intensive oxide. Due optical electrical properties, found many different uses such as solar cells, light emitting diodes, gas sensors flat panel displays. Recently, various carried out improve create new areas use by doping elements.
