摘要：

The transmittance spectra of PbTe films representing heterophase junctions from a metastable (CsCl- or GeS-type phase) to the stable NaCl-type phase are investigated at different temperatures in the range 77-320 K. From the quantitative interpretation of the spectra the energy gaps of PbTe metastable phases, their temperature coefficients, and the refractive index dispersions are determined.
