| Strong modification of the optical spectra near the band-gap edge is observed in Cd1-xFexTe 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 (A0, x) acceptor bound exciton emission in undoped CdTe to the free exciton luminescence in Cd1-xFexTe solid solutions. |
