A model system consisting of Eu3+ as the activator ion and BaZrO3 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.
