Abstract :
This paper presents a detailed PL study of Fe2+ related four zero-phonon (ZP) lines and their related phonon sidebands. Four zero-phonon transitions at ≈2800 cm-1 along with the accompanying phonon sidebands extending down to 2400 cm-1. There are two prominent regions in the phonon sidebands. One is ascribed to coupling to acoustic-type phonons (2700 cm-1 region), the other is due to coupling to optic-type phonons (2500 cm-1 region). Beside broad coupling with lattice modes, there are several groups of lines. They are ascribed to resonant modes, impurities induced gap modes and local modes
