Infrared photoluminescence measurements have been made of a number of HgTe-CdTe superlattice samples as a function of temperature from liquid He to room temperature. The experimental results are compared with calculations of the band gap of these materials and the effects of layer thicknesses, valence-band offset, effective mass, and Hg in the CdTe layers are investigated. The data are in reasonable agreement with the calculations for zero (or small) valence-band offset and no Hg in the CdTe layers.
