[Effect of Al3+ on luminescence intensity of Tb in silica glasses].
The silica glasses doped with Tb3+ and Al3+ iones was synthesized through Sol-Gel process in this paper. The effect of Al3+ on luminescence properties of Tb3+ were studied. The results show that no obvious effect of Al3+ on the emission peak position of Tb3+, but the emission intensity of Tb3+ doped Al3+ by sol-gel process increased obviously for all samples. The emission intensity of 1% Al-99% SiO2 glass was 5 times larger than that of 100% SiO2 glass. We concluded that the relation between the energy levels of Tb3+ and the energy levels of Al3+ may be appropriate for the energy transfer, the function of Al3+ was to absorb efficiently energy and to transfer fully to Tb3+.
