A novel method with vertical pulsed-laser deposition(VTPLD)is proposed to prepare nanoparticle and nanofilm.And ZnO thin films on glass substrates are prepared by VTPLD at room temperature in atmosphere.The surface morphology and structural information of the films are investigated by scanning electron microscopy(SEM)and X-ray diffraction(XRD).The property of photoluminescence of film is also studied.The results show that ZnO nanometer thin film and ZnO microporous continuous thin film are obtained under different laser power of 13 W and 21 W respectively.There is main peak at(002),which shows that the ZnO film has better orientation along c axis.Photoluminescence intensity changes as the function of laser power,and the maximum peak at 412 nm presents blue emission.
