The exciton luminescence spectra of CdTe/ZnTe heterostructures containing two thin CdTe layers separated by barriers of different thickness were studied. The complex temperature dependence of the intensity of luminescence from these layers in its underbarrier and abovebarrier excitation led to the conclusions about the effect of the thickness of the barriers on the energy transfer between the CdTe layers and gave the possibility to observe, at specific temperatures, the implementation of a resonant-type excitation. The dependence of the shape of the exciton emission contours on the excitation level gives information about the real structure of CdTe layers with the monolayer thickness of 1.5 and 4.0 monolayers.
