对半绝缘n型和p型InP：Fe进行了YAG激光激发下的光致发光、光致发光激发光谱以及热（和光）电容瞬态测量。计算结果与差距中Fe ~（2+）的单电荷态的热力学和光学性质一致，并提出了相应的能级方案. 0.35 eV的中心内Fe 2+跃迁的激发是由于Fe 3+的电子俘获，使Fe 2+中心处于5 T2激发态，并辐射弛豫到5E基态。一个新的带在0.5 eV的铁有关的报告，并讨论了它的起源。
Photoluminescence under YAG laser excitation, photoluminescence excitation spectra and thermal (and optical) capacitance transient measurements have been carried out on semi-insulating, n and p type InP:Fe. The results are found to be consistent with the thermal and optical properties of a single charge state Fe2+of iron in the gap for which we propose an energy level scheme. Excitation of the 0.35 eV intracentre Fe2+transition is due to an electron capture by Fe3+giving an Fe2+centre in the5T2excited state which relaxes radiatively to the5E ground state. A new band at 0.5 eV related to iron is also reported and its origin is discussed.
