Abstract: 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 m SiO$_{2}$/GaN:Eu$^{3+}$ particles show a group of lines characteristic of intracenter transitions in Eu$^{3+}$.

Keywords: Gallium Nitride (GaN), Nanocomposite Particles, Intracenter Transitions, Heterogeneous Synthesis, Gallium Oxide.
