摘要The luminophors MeO-SiO_2:Eu3+,Bi3+and MeO-SiO_2Bi3+(Me=Mg.Sr)were synthesized at relatively lower temperature by the sol-gel method using the silica sol as a source of silica.The optimum composition and synthesis conditions were obtained by studying the excitation and emission spectra and the effects of energy transfer from the Bi3+ions to the Eu3+ions.
