A modified surface was obtained on wide-gap II-VI compounds. The methods of thermal annealing for cadmium chalcogenides and chemical etching for the first time obtained heterolayers of atypical hexagonal modification of α-ZnSe have been improved. AFM topograms of surface nanostructures have been investigated and comprehensive studies of optical and luminescent properties have been carried out. The emission spectra were determined in the photon energy range 1.4–3.6 eV and the important role of recombination processes in the formation of the A band in the edge region was established. The dominant role of quantum-dimensional processes in the formation of the obtained B band of intense radiation in a wide spectral region of the visible and ultraviolet ranges has been established.
