Abstract

The decay processes of light-induced absorption in one undoped and two Ce-doped BaTiO₃ crystals were observed. Two decay times were found, they had not a strong dependence on intensity in our experiment. We present a model with two different shallow trap centers to explain the experimental results. The theory and experimental results agree well. The light-induced absorption coefficients and decay times corresponding to the two shallow levels are also given.
