Abstract

In this paper, the radiationless transition of the excited state 5D0 of Eu3+ in SBN crystal has been studied by observing the temperature dependence of the fluorescence lifetime of 5A0→7F2 emission band. The temperature quenching effect of 5D0→7F2 band is mainly due to that the minmum energy of the charge-tranfer state (CTS) of Eu3+ is so low that 5D0 state can be activated thermally to CTS and then transfers to 7F state via CTS with radiationless transition.
