Abstract
In order to prepare good crystalline quality of Cu-doped ZnO thin films and study its structure,the film was prepared by means of the pulsed laser deposition method with the Si substrate at different temperatures.In experiments a better crystal quality of Cu-doped ZnO thin film was prepared successfully.The specimens were measured and analyzed by means of Xray diffraction,scanning electron microscopy and photoluminescence spectrum.It was found that the prepared specimens appeared highly c-axis oriented,and the surface morphology of thin film was uniform and dense with the substrate at 300℃.In their photoIuminescence spectrums,besides the peak UV luminescence around 380nm,there was a peak blue light-emitting band around 460nm,which made it possible to emit blue light with ZnO films in practice.The results show that the crystal quality is seriously dependent on the growth temperature.
