    Preparation, morphology, and luminescent properties of europium-doped nanodispersed scandium sesquioxide
    摘要:
    Scandium sesquioxide-based solid solutions of composition Sc-2 (-) 2xEu2xO3 (0.005 <= x <= 0.05) were prepared by thermolysis of Sc-1 (-) Eu-x(x)(CH3COO)(3) and by reacting mixtures of scandium and europium nitrates with ethylene glycol. Thermal decomposition of Sc-1 (-) Eu-x(x)(CH3COO)(3) was found to yield Sc2 - 2xEu2xO3 with the shapes of aggregates atypical of the cubic structure of this oxide, and the reaction products of scandium and europium nitrates were found to have a loose spongelike structure. A spectroscopic study showed that Sc2 - 2xEu2xO3 and Sc1 - Eu-x(x)(CH3COO)(3) are potential luminescent materials active in the visible spectral region. The tervalent europium in the Sc(2 - 2x)Eu(2)xO(3) structure is the source of strong red emission (D-5(0)-> F-7(2)) and can be used in fluorescent lamps, colored lightning, and optoelectronic devices.
