Abstract

Nanodimensional luminescent CdS-based grains on the surface of narrow-bandgap inclusions can be formed under certain regimes of annealing of a heterophase film based on a wide-bandgap CdS with narrow-bandgap Pb x Cd1 − x S inclusions (with x no less than 0.94). The annealing leads to a change in the luminescent properties of the initial material in the visible spectral range and in the distribution of luminescent regions on the map of cathodoluminescence. Processes leading to these changes in the phase composition are described using data of Auger electron spectroscopy.
