摘要：

<正>Phosphor of KMgF3:Ce3+is synthesized through solvothermal method at 180℃and characterized by means of X-ray powder diffraction（XRD）and environment scanning electron microscopy（ESEM）.X-ray photoelectron spectroscopy（XPS）is applied to the study of the energy band structure of KMgF3:Ce3+and confirms the oxygen content of the product is very low.The fluorescence spectra of the rare-earth ion-doped KMgF3 is investigated by the fluorescence spectrophotometer.In the emission spectra,there is a broadband emission with a maximum center located at 306 nm arising from d-f transition of Ce3+in the host.This will be useful for ultraviolet tunable lasers.
