Preparation and characterization of a new phosphor Lu²O ₃:Eu³⁺

Europium-doped Lu₂O₃ nanocrystalline powders were prepared via a novel solution combustion route, with glycine as the fuel. The crystalline size and specific surface area of the combustion derived powders are strongly dependent on the glycine-to-nitrate ratio, which can control the combustion flame temperature. XRD, SEM, TEM and BET were used to characterize the phosphors and the photoluminescence was also investigated. Lu ₂O₃:Eu³⁺exhibits narrow-band red emission extending from 580-700nm with a sharp peak at 611nm, corresponding to ⁵D₀ ⁷F₂ transition of the Eu ³⁺ ion.
