摘　　要：Phosphor of KMgF3：Ce^3＋ 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：Ce^3＋ 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 Ce^3＋ in the host. This will be useful for ultraviolet tunable lasers.Phosphor of KMgF3：Ce^3＋ is synthesized through solvothermal method at 180 ℃ and characterized by means of X-ray powder diffraction （XRD） and environment scanning electron microscopy （ESEM）.
