Y 2 O 3 :Eu nanocrystals in the size range 70–100 nm have been synthesized with a photoluminescence efficiency 10–20 % higher than that of the commercial bulk material. The Figure shows nanocrystalline Y 2 O 3 :Eu after firing of the precursor material. It can be seen that the crystals are structurally perfect, i.e., no defects are found within the crystal structure.
