Radiative recombination in n-Hg_1-xCd_xSe (0.2≤x≤0.32) in the temperature range 4.2-17 K and in magnetic fields up to 8 T was investigated. The concentration N_d-N_A of uncontrollable impurities was equal to (2-6) × 10¹⁶ cm^-3. The photoluminescence spectra of n-Hg_1-xCd_xSe at 4.2 K in the absence of a magnetic field have a three-band structure. The observed emission bands were identified on the basis of integrated photoluminescence and photoelectric investigations and the effects of the temperature and a magnetic field: The short-wavelength A band is due to excitons bound on donor impurities, the B band is due to an exciton bound on composition fluctuations, and the long-wavelength C band is due to donor-acceptor recombination. The energy position of the donor was at 1.9 meV and the acceptor states were at 90 and 8 me V.
