- 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 $\text{}^{5}D_0$ emission are evaluated on the basis of Judd-Ofelt theory.
