## Abstract In this article we demonstrate the synthesis of Eu^2+^‐doped GaN/SiO~2~ nanocomposites using a simple solid state reaction and their use in light‐emitting devices. The nanocomposite exhibits a bright blue luminescence when excited in the UV region (quantum yield = 23 %). The origin of t
