Preparation and Luminescence of Y2O3:Eu3+ Nanopowder
Eu3+ doped Y2O3 nanopowder was prepared by a novel complex precipitation process in which the mixture of ammonium water and ammonium hydrogen carbonate was adopted as complex precipitant. The precipitant precursor and the resultant powder were characterized by FT-IR, XRD, SEM and TEM. The resultant weakly agglomerate and spherical particles have a uniform grain size about 20nm after calcined at 850°C for 2 hours. 3mol% Eu3+ doped Y2O3 nanopowder shows an intense red luminescence at 612nm under UV excitation.
