A nanocomposite in the form of monodisperse spherical mesoporous silica particles (mSiO_2) filled with GaN:Eu^3+ is synthesized by the template method. The method is based on the capillary impregnation of pores of mSiO_2 particles with a melt of crystal hydrates of gallium and europium (0.22 wt %) nitrates, followed by thermal decomposition and ammonia treatment. It is shown that nanocomposite particles contain hexagonal GaN:Eu^3+, are of spherical shape, monodisperse and do not coalesce with each other. The photoluminescence spectra of the mSiO_2/GaN:Eu^3+ particles show a group of lines characteristic of intracenter transitions in Eu^3+.
