Abstract

An analysis of the published data on the electrical properties of the alloys SmSe-NdSe and EuSe-LaSe is used to propose energy band schemes for these substances. The absorption spectra of films of EuS, EuSe, and of EuSe-LaSe alloys, obtained by thermal evaporation under vacuum, are presented, as well as the diffuse reflectance spectra of EuS and EuSe powders. These optical studies are used to suggest which electron transitions are responsible for the light absorption in these semiconductor compounds.
