摘要：

We present Fourier transform infrared photoluminescence (PL) and absorption studies on GaAs:Fe to analyze the origin of the Fe-related emission at 3057 cm-1. Temperature-dependent PL spectra show additional hot lines and a characteristic phonon sideband linked to this Fe-related peak. Time-resolved studies, using the 1.06-mu-m line of a Nd:YAG laser for excitation, reveal a decay time of 1.9 +/- 0.3 ms. The long lifetime and the fine-structure splitting fit a model where the transitions take place between the 4T1 excited state and the 6A1 ground state of Fe3+ (3d5) in tetrahedral environment.
