本文利用远红外吸收和光致发光的测量方法研究了具有特征发光特性的β-FeSi_2晶体的声子性质，讨论了它们之间的相关性。研究发现，声子态与发光效率之间存在系统相关性，能量大于1.44 meV的声子可以有效地耦合到β-FeSi 2晶体红外光发射的光学间接跃迁。
We have investigated phonon properties of some β-FeSi2crystals with characteristic light emission properties by using measurements of far-infrared absorption and photoluminescence in order to discuss a correlation between them. It has been found that there is a systematic correlation between phonon states and light emission efficiency and that the phonons above the energy of more than ∼44 meV may be effectively coupled to the optical indirect transition for the IR light emission from β-FeSi2crystals.
