Strong modification of the optical spectra near the band-gap edge is observed in Cd_{1-x}Fe_{x}Te crystals as compared to the spectra of a pure compound. The evolution of the luminescence spectra at the increase in Fe concentration is represented by the change of radiative recombination channels from dominantly (A^{0}, x) acceptor bound exciton emission in undoped CdTe to the free exciton luminescence in Cd_{1-x}Fe_{x}Te solid solutions.
