LaF3:Ce3+/Tb3+ particles were synthesized by using solvothermal method in the mixed solvents of etha?nol and oleic acid at 190℃ for 6h. The SiO2 was coated on the LaF3:Ce3+/Tb3+ particles. The as-prepared LaF3:Ce3+/Tb3+ crystals were investigated by X-ray diffraction,Fourier transform infrared spectroscopy and fluorescent spec?troscopy. The powder X-ray diffraction (XRD) showed that the PDF of LaF3: Ce3+ /Tb3+ crystal was 77-2028. IR ab?sorption spectra showed that the SiO2 is on the surface of LaF3:Ce3 +/Tb3 + crystals. The fluorescent spectra showed that the shape of emission peak was change and the main fluorescent peak of particles of modified LaF3:Ce3 +/Tb3 +were red-shift.
