| 中文摘要 | Spectral and temporal characteristics of light-induced absorption for an undoped and a Rh-doped as-grown BaTiO3 crystal were investigated and compared. Two dark-decay time constants corresponding to two shallow levels were observed: 40 ms and 1.2 s for undoped BaTiO3 and 39 ms and 3.4 s for Rh-doped BaTiO3. The light-induced absorption spectra were resolved into two components according to the dark-decay time constants. The resolved spectra reveal that one shallow level in Rh-doped BaTiO3 and one in undoped BaTiO3 are caused by a same impurity defect. The thermal activation energies of these levels were determined to be 0.53 and 0.7 eV for undoped BaTiO3 and 0.57 and 0.8 eV for Rh-doped BaTiO3. The 0.8-eV shallow level in BaTiO3:Rh is caused by Rh4+/5+; the other level, 0.57 eV, is the one that has the same defect origin as the 0.53 eV level in undoped BaTiO3. Other parameters for the shallow levels are also given. (C) 1998 Optical Society of America. |
