| 摘 要： | 研究了(Gd3+,Ce3+/Ce4+,Eu3+)对Tb3+掺杂硅酸盐玻璃发光性能的影响.结果表明:Tb3+掺杂硅酸盐玻璃可以发出弱蓝光(400～460 mm)和较强的绿光(480～600mm).Gd3+对Tb3+的发光起敏化作用,可提高TB3+掺杂硅酸盐玻璃的发光强度.在空气中熔制的玻璃中Ce3+和Ce4+同时存在,Ce3+对Tb3+发光起敏化作用;而Ce4+对Tb3+发光起淬灭作用.由于Ce4+比例比较高,CeO2加入导致TB3+发光强度降低,同时也缩短了Tb3+发光余辉.加入Eu2O3时,Eu3+自身发光分散了激发Tb3+发光的能量,使Tb3+的特征发射强度降低.

| Abstract: | The effect of rare earth ions(Gd3+,Ce3+/Ce4+,Eu3+) on luminescence of Tb3+ doped silicate glasses was investigated.Results showed that Tb3+ doped silicate glasses can emit weak blue(400-460 nm) and strong green(480-600 nm) luminescence.Gd3+ can enhance the luminescence of Tb3+ in silicate glasses by the energy transfer in resonance manner from Gd3+ to Tb3+ emission center.Ce3+ and Ce4+ ions coexist in Tb3+ doped silicate glasses fabricated at air atmosphere when CeO2 is added.Ce3+ ions sensitize Tb3+ ions a... |
