中文摘要：

研究了Gd^3＋，Ce^3＋／Ce^4＋，Eu^3＋对Tb^3＋掺杂硅酸盐玻璃发光性能的影响。结果表明：Tb^3＋掺杂硅酸盐玻璃可以发出弱蓝光（400～460nm）和较强的绿光（480～600nm）。Gd^3＋对Tb^3＋的发光起敏化作用，可提高Tb^3＋掺杂硅酸盐玻璃的发光强度。在空气中熔制的玻璃中Ce^3＋和Ce^4＋同时存在，Ce^3＋对Tb^3＋发光起敏化作用；而Ce^4＋对Tb^3＋发光起淬灭作用。由于Ce^4＋比例比较高，CeO2加入导致Tb^3＋发光强度降低，同时也缩短了Tb^3＋发光余辉。加入Eu2O3时，Eu^3＋自身发光分散了激发Tb^3＋发光的能量，使码Tb^3＋的特征发射强度降低。

英文摘要：

The effect of rare earth ions （ Gd^3＋ , Ce^3＋/Ce^4＋ , Eu^3＋ ） on luminescence of Tb^3＋ doped silicate glasses was investigated. Results showed that Tb^3＋ doped silicate glasses can emit weak blue （400-460 nm） and strong green （480 -600 nm） luminescence. Gd^3＋ can enhance the luminescence of Tb^3＋ in silicate glasses by the energy transfer in resonance manner from Gd^3＋ to Tb^3＋ emission center. Ce^3＋ and Ce^4＋ ions coexist in Tb^3＋ doped silicate glasses fabricated at air atmosphere when CeO2 is added. Ce^3＋ ions sensitize Tb^3＋ ions and strongly strengthen the luminescence emitted by Tb^3＋ ions. However, Ce^4＋ ions have quenching effect on the luminescence of Tb^3＋ ions. The luminescent intensity of Th^3＋ and Ce^3＋/Ce^4＋ codoped silicate glass is much lower than that of Th^3＋ doped silicate glass because the concentration of Ce^4＋ ion is high. The lives of afterglow will be shorten in Tb^3＋ doped silicate glasses owing to the existence of Ce^4＋ ＋ e=Ce^3＋. The luminescent intensity of Tb^3＋ doped silicate glass decreases when Eu2O3 was added.
