Over the past 20 years magneto-optical studies in semiconductors have proven capable of accurately determining energy band parameters because of the optical transitions that occur between magnetically quantized electronic or impurity states. In addition, interesting features in the optical and photoconductive properties are observed that are caused by the electron-phonon interaction. Here we present some novel features of the magneto-optical properties of n-InSb that represent a new development to this well-established field of solid state physics. Resonances are observed in the CO2 laser-induced magnetophotoconductivity whose positions depend strongly upon photon energy. The results provide the first direct evidence of emission of five optical phonons during the energy relaxation process of the photo-excited electrons created by a CO2 laser in n-InSb. All observed transitions can be described with one single set of band parameters.
