Wang Zhi-hua, Zhao Shu-yun, Wei Jian-jiang, Qi Dong-juan, Wu Yuan. EFFECT OF Ce ON Tb<sup>3+</sup> ION LUMINESCENCE PROPERTIES IN YAG HOST[J]. Chinese Journal of Luminescence, 1982,3(3): 46-53DOI:
It was experimentally found that incorporation of Cein YAG:Tb remarkably enhances the

F transition intensity of Tb
3+
ion
thus
changes relative energy distribution of emission spectrum
rises luminescence brightness
improves current and voltage characteristics
reveals a potentiality of improving the luminescence properties of commercial P53 phosphor. It has been shown that this enhancement effect can be attributed to energy transfer from Ce
3+
to Tb
3+
ions. The mechanisms of energy transfer above Were discussed. The transfer process was analysed.
