Cd x Hg 1−x−y Mn y Se solid solutions are promising materials for filters operating in the near- and middle-IR regions of the spectrum

Transmission spectra of new fourfold semimagnetic semiconductors Cd_xHg_1−x−yMn_ySe (x≤0.6; y≤0.01–0.1) at 77 and 300 K and the effect of annealing of them in vapors of the components on their optical properties were investigated. It is shown that Cd_xHg_1−x−yMn_ySe crystals possess high light transmission (≥60%) and can be used for devices operating in the near- and middle-IR regions of the spectrum.
