The physicochemical properties of low-dimensional structures based on cadmium telluride obtained by the colloidal synthesis method are investigated. It is established that the change in the ratio of the [Cd2+]: [Te2] concentrations in the reaction medium significantly influences the properties of the colloidal synthesis of CdTe NCs. It is shown that the ratio of 8: 1 is the optimal ratio of the concentrations of [Cd2 +]: [Te2] to obtain NCs of CdTe. It is shown that the use of a vinyl acetate-acrylate copolymer as a matrix material for the transfer of NCs CdTe from colloidal solutions allows obtaining non-toxic Nanoheterogeneous film structures, characterized by satisfactory optical properties. The main photoluminescent characteristics of the materials under study are analyzed.
