Scientific research in the field of nanostructure physics and condensed matter optics. Established the role of impurity recombination in the formation of nonlinear optical properties of semiconductor crystals. For the first time, he discovered and investigated the inhomogeneous broadening of the optical spectra of semiconductor nanocrystals in dielectric matrices and established a number of fundamental laws governing the evolution of the properties of nanoparticles during the transition from low-atomic clusters to bulk solids. Investigated the interaction of electromagnetic radiation with quantum systems in the conditions of spatial limitation of electromagnetic waves. He proposed to use colloidal crystalline nanostructures as a prototype for creating "photonic crystals", discovered and investigated the change in the probability of quantum transitions of molecules in such nanostructures, due to a change in the density of photonic states. Based on the analysis of quantum processes in nanostructures, he proposed a mechanism for amplifying resonant and Raman scattering of light in nanostructures, as well as practical methods for increasing the sensitivity of spectroscopy of giant Raman scattering and the efficiency of light-emitting solid-state structures. Established the basic laws of radiation propagation in nanostructures with fractal geometry, proposed principles for coding information based on the characteristic spectra of classical waves and quantum particles in nanostructures.
Author of about 200 scientific papers, incl. 3 monographs. Under his editorship, foreign publishers published 6 collections of scientific papers on the physics of nanostructures.
Prize of the National Academy of Sciences of Belarus in 2010.
