Phosphor of KMgF_3: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 KMgF_3:Ce~(3+)and confirms the oxygen content of the product is very low.The fluorescence spectra of the rare-earth ion-doped KMgF_3 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.
