| 中文摘要 | crystalline y2o3:eu is of paramount significance in rare earth materials and research on luminescence spectra. in this work, the nanocrystalline y2o3:eu was coated with silica by a facile solid state reaction method at room temperature. the transmission electron microscope (tem) photographs showed that the prepared y2o3:eu particle is polycrystalline with the size of 20 nm, the size of silica-coated particle is about 25 nm. the xps spectra indicated that the silica layer is likely to interact with y2o3:eu by a si-o-y chemical bond. the luminescence spectra showed that the intensity of ground samples is lower than that of unground ones, the intensity of silica-coated phosphors is higher than that of the ground samples, while almost the same as that of the unground ones. therefore, the silica coating decreases the surface defects of nanoparticles of the nanocrystalline y2o3:eu, thus increasing their luminescent intensity. |
