Abstract
The reflection spectra of powder preparations of cadmium telluride and cadmium selenide with different contents of overstoichiometric components have been investigated in the range of 800–1700 nm. The reflectance is found to be maximum for samples with compositions close to stoichiometric. An increase in the concentration of overstoichiometric cadmium more radically reduces the reflectance in comparison with preparations containing excess chalcogen. It is shown that halftone images in the near-IR range can be formed by using of these materials.
