Investigation of optical properties and processes of nonlinear interaction of intense laser radiation with semiconductor, metal and metal oxide nanostructures and their composites in order to find the latest materials with high nonlinear optical parameters suitable for their application in modern optoelectronics; study of the quantum-dimensional effect of excitons in the quantum dots of Zn and Cd chalcogenides and its influence on the strength of interaction between them, as well as on the mechanisms of electronic excitation energy transfer in various complex geometric surfaces. Methods of low- and high-temperature optical spectroscopy (absorption, photoluminescence with spatial resolution) Raman and infrared spectroscopy; methods of nonlinear refractometry: degenerate four-wave interaction (DWI), nonlinear lens (Z-scanning), self-influence of laser radiation; computer modeling; stationary and time-resolved absorption and emission spectroscopy of colloidal solutions and solid films of quantum dots; differential scanning calorimetry m Product Description popup.authors Bondar Mykola Volodymyrovych Borshch Anatoliy Oleksandrovych Brodyn Mykhailo Semenovych Volovyk Mykola Volodymyrovych Gayvoronsky Volodymyr Ya.
