Preparation and Application of ZnO Films

The paper introduces ZnO about its crystal structure and photoelectric property,as well as preparation methods about ZnO films and the relative merits of the methods.Sol-gel thchnique is a greatly welcomed chemial method because of its low cost,simple technics,easy to handle and to controtl doping.ZnO films and doping ZnO films have been wide used for its photoelectric property and have a wide developmental foreground.
