The complex fluoride LiBaF3and LiBaF3:M(M=Eu, Ce) is solvothermally synthesized at 180°C and characterized by means of X-ray powder diffraction, scanning electron microscopy, thermogravimetric analysis and infrared spectroscopy. In the solvothermal process, the solvents, molar ratios of initial mixtures and reaction temperature play important roles in the formation of products. The excitation and emission spectra of the LiBaF3:M(M=Eu,Ce) have been measured by fluorescence spectrophotometer. In the LiBaF3:Eu emission spectra, there is one sharp line emission located at 360nm arising from f→f transition of Eu2+in the host lattice, and typical doublet 5d–4f emission of Ce3+in LiBaF3powder is shown.
