Abstract Recombination radiation in Cd 3 (As x P 1− x ) 2 solid solutions near cadmium phosphide ( x ⪅ 0.1) is studied. A complex structure of the stimulated emission spectra in Cd 3 (As x P 1− x ) 2 single crystals is detected. It is shown that for Cd 3 P 2 the width of emission spectrum and its position relative to the transmission edge may be adequately described in terms of a direct interband‐transition model. The same model is used to calculate the luminescence I cv1 (ω) and the optical transmission T cv1 (ω) in the presence of a small (i.e. up to 5% of the Brillouin zone size) K 1 shift between the extrema of the heavy hole valence band V 1 and conduction band C. It is shown that at k 1 ≠ 0 the dependence I cv1 (ω) may have two maxima. The structure of stimulated emission spectra and the reference data on luminescence in Cd 3 (As x P 1− x ) 2 single crystals are interpreted taking into account the calculations carried out in this work.
