As for Ce + and Tb + co-doped glasses, the luminescence inten- sities of Ce + and Tb + both decrease. This could be related to the competitive absorption between Ce + and Tb + because their excita- tion peaks pile up on the wavelength of — 8 nm.

对于Ce +和Tb +共掺杂玻璃,Ce +和Tb +的发光均有所减弱,这可能是由于Ce +,Tb +二者在 ～ 8nm波长处有激发峰的重叠,而存在竞争吸收所致。
