摘要：

Previous studies of the optical absorption bands attributed to the 3A2 to 3T1(F) internal transitions of V3+ ions in GaP, GaAs and InP have shown that a very strong T(X)t2 Jahn-Teller effect is active in the 3T 1(F) state. An analysis is presented for the GaP:V3+ system which reconciles the structure of the accompanying zero-phonon line in terms of second-order Jahn-Teller spin-orbit coupling contributions, with the strength of the coupling deduced from the properties of the band. In the cases of GaAs:V3+ and InP:V3+, it is proposed that strong coupling to e modes is also present.
