| Abstract: | The luminophors consisted of(Ca-Zn)O-Al_2O_3-SiO_2 were prepared using asol-gel method following by activation by Eu~(3+) and sensitization by Bi.~(3+) The optimum conditions of preparation and chemical compositions of the products are confirmed through powder diffraction and flourescence measurements. The energy transfer from Bi~(3+) to Eu~(+3) is briefly discussed. |
