Abstract: In this paper, 1-14SrO-0.5Al2O3-4.5SiO2:0.05Eu3+, 0.005Bi3+ was prepared at 850℃by the sol-gel method. Optimum conditions wcre judged by the relative intensity of lumi-nescence.Transition of gel to luminophor was investigated by TG:DTA, XRD and IR spectroscopy.The luminescent properties of Eu3+and the energy transfer from Bi3+to Eu3+were discussed according to the emission and excitation spectra of the luminophor.

Key words: luminophor, bismuth, europium doped aluminosilicate, fluorescence, energy transfer
