摘要：

Based on the developed technique for synthesizing spherical mesoporous particles of yttrium oxide with a size dispersion of 10-15% and methods for infiltrating active components into them, spherical nanocrystalline particles of composition Y2O3-ZnO have been synthesized. The nanocomposite structure has been studied, and the spectra of diffuse reflection and photoluminescence of heteroparticles, as well as the stimulated emission spectra of zinc oxide excitons, have been analyzed after annealing at various temperatures. The formation of ZnO nanocrystals in Y2O3 sphere pores is observed during material synthesis with a single infiltration procedure. The lasing is associated with a change in the effective refractive index and local photon density of states in phosphor nanoparticles, i.e., spherical optical cavities.
