The structures were grown by molecular-beam epitaxy and emitted light with wavelength of 1.5 to 4.3¦Ìm at room temperature. It is suggested that observation of photoluminescence of the narrow-gap semiconductor at high temperatures and the specific shape of photoluminescence spectra can be explained by taking into account HgCdTe alloy disorder as is the case, for example, in structures based on III-nitrides. Requirements for technology considerations for the optically-pumped high-temperature infrared emitters based on HgCdTe are discussed.
