ZnO,as a novel material of Ⅱ-Ⅵ semiconductor,has excellent optical and electrical properties. ZnO-based thin films have considerable potential applications in many fields,such as UV light emitter,spin functional devices,gas sensors,transparent electronic and surface acoustic wave devices. Firstly,the relevant knowledge of ZnO and pulsed laser deposition is introduced,then recent advances on ZnO-based films,such as p-ZnO,p-n junction,Zn_1-xMg_xO thin film,Zn_1-xCd_xO thin films and magnetic ions doped ZnO thin films are illustrated with the emphasis
