Registration Date 03-07-2023 Organization Lesya Ukrainka Volyn National University popup.description2  The development of technology for obtaining glasses and single crystals, the optical elements of which will be used in non-linear optical devices of the infrared (IR) range: lasers, lidar, military equipment and which are dual-purpose materials. The work solvs the important issues of security and defense capability of Ukraine, as the mechanisms responsible for linear and nonlinear optical processes in glasses and single crystals of compounds formed in the Ag2S – Ge(Sn)S(Se)2 – As(Sb)2S(Se)3, Ag2S – GeS2 – Ga2S3, Tl2S – GeS2 – Ga2S3, Ga2S3–GeS2–As(Sb)2S3, AgCl(Br,I)–Ga(In)2S3–La2S3 doped with REM (Pr, Nd, Dy, Er), in order to improve their work. The optimal compositions of glass matrices and concentrations of alloying impurities, optimal parameters for growing high-quality single crystals will be determined, which will ensure the specified parameters of radiation of REM atoms in the IR range. This project is based, among other things, on the authors’ results of previous fundamental and applied research, and the final product is materials with improved physical and physicochemical characteristics, as a basis for efficient light emitters and converters in the near and mid-IR ranges of the spectrum.
