摘要：

The spectroscopic properties of Mn3+ and Mn2+ ions have been studied in Mn:YAlO3 codoped with Ce and singly Mn-doped YAlO3. Mn3+ absorption at the E-5 --> T-5(2) transition, the transition between the Jahn-Teller split components of the ground state E-5, and Fano antiresonance mixing between the E-3 and T-5(2) states have been investigated. The weak absorption at 0.41 mu m was attributed to the (6)A(1) --> (4)A(1) E-4 transition of Mn2+. Green emission peaking at 530 nm excited with x rays was attributed to the T-4(1) --> (6)A(1) transition of Mn2+. The reduction of Mn2+ concentration in photoexposed samples may imply the presence of Mn+ ions in YAlO3. (C) 1999 Optical Society of America [S0740-3224(99)02302-4].
