In the present work we explored the possibility of obtaining Y_2O_3:Eu^{3+} μm-size particles by an ultrasonic spray pyrolysis method. As-prepared sample constitutes of spherical, hollow particles with an average size of 1 to 2 μm. Pure, well crystalline, cubic Y_2O_3 is formed after additional thermal treatment at 800°C for 2 h. A detailed optical investigation has been done with photoluminescence measurements in the energy and time domains. Experimental intensity parameters, transition rates and quantum efficiency of the ^{5}D_0 emission are evaluated on the basis of Judd-Ofelt theory.
