Abstract: The luminophors consisted of (Ca-Zn)O-Al2O3-SiO2 were prepared using asol-gel method following by activation by Eu3+ and sensitization by Bi3+ The optimum conditions of preparation and chemical compositions of the products are confirmed through powder diffraction and flourescence measurements. The energy transfer from Bi3+ to Eu+3 is briefly discussed.
