| Abstract: | The luminophors, 2.686ZnO-1.6Al2Os-5Si02:0.05Eu3+, 0.007Bi3+, were synthesised using the sol-gel method. The transfer process from sol to gel were studied by small angle X-ray diffraction, IR spectra, X-ray powder diffraction and TG-DTA. The luminescent properties of the sample and the energy transfer from Bia+ to Eu3+ were discussed according to the emission and excitation spectra of the luminophors. |
