Paper Abstract

Grating dark decay in an undoped, a Rh-doped, three Ce-doped and a (Ce, Rh)-doped BaTiO3 crystals were systematically studied at room and elevated temperatures. Depth of the impurity levels and the dark decay time constant in these crystals were determined. The result show that the impurity levels related with photorefraction in the doped crystals have different origins from that in the undoped sample and the photorefractive center was caused by doping. In the (Ce Rh)-doped crystal, the results suggest that there are two deep levels caused by the dopings of Ce and Rh.
