Abstract
Phosphors of BaLiF3 doped with Eu or/and Ce were solvothermally prepared at 200 °C for 5 d and characterized by means of X-ray powder diffraction (XRD) and environment scanning electron microscopy (ESEM). The excitation and emission spectra of the rare earth ions doped BaLiF3 were measured by fluorescence spectroscopy and the effects of Ce3+ ions on the luminescence of Eu2+ ions were investigated. In the co-doped Eu2+ and Ce3+ system, the emission intensity of Eu2+ ion gradually increased with the Ce3+ concentration increasing, and the enhancement of Eu2+ fluorescence was due to efficient energy transfer from Ce3+ to Eu2+ in the host.
