The spectra of exciton emission in a series of periodic structures with ultrathin Cd0.9Mn0.1Te inclusions in the Cd0.7Mg0.3Te matrix have been studied. The complex structure of the luminescence spectra and their relation to the luminescence excitation spectra indicate large-scale fluctuations in thickness of nar-row-band-gap layers. Two types of temperature dependences of the luminescence intensity of localized excitons are found: (1) the complete suppression of emission above 80 K and (2) the relative enhancement of temperature-insensitive low-energy band that corresponds to local bulges in planar Cd0.9Mn0.1Te layers.
