摘要：
ZnO:EU3+ films were obtained by dip-coating method and influence of heat treatment on luminescent properties was investigated. Emission and excitation spectra revealed that the organic and nitrate molecules, which adhered on the surface of films when the samples were treated at lower temperatures (300 degrees C-400 degrees C), played an important role on the luminescent properties. At higher temperatures (500 degrees C-800 degrees C), the luminescence spectra of ZnO and EU3+ were quite different with those treated at lower temperatures. Energy transferred from ZnO host to Eu3+ was obviously observed in the emission and excitation spectra. The luminescence mechanism was discussed briefly.
