Europium doped yttrium oxide phosphors were synthesized by a rapid microwave-assisted solvothermal method. The microwave processing time for synthesizing the precursors of Y2O3:Eu3+ powders was as short as 5 min. After calcination at 600 degrees C, a well-crystallized pure phase of Y2O3:Eu3+ was obtained. The morphology of the precipitated powders was spherical and composed of nano-sized grains. As the microwave irradiation time was increased, the average particle size of the spherical powders increased, and the crystallinity of heat-treated powders was also enhanced. The synthesized powders retained the spherical morphology after heating treatments. An intense red emission at 611 nm was assigned to the D-5(o)-F-7(2) transition of Eu3+.
