A model system consisting of Eu 3+ as the activator ion and BaZrO 3 as the host lattice is employed to demonstrate the potential of the vapor diffusion sol−gel method as a hydrolytic approach to the synthesis of fluorescent alkaline‐earth perovskite oxide nanocrystals under ultrabenign conditions. The resulting nanocrystals are suitable precursors for nanostructured red‐emitting phosphors.
