Summary, etc. <p>In this study, Y<sub>1.50</sub>Sc<sub>0.50</sub>O<sub>3</sub>:Sm<sup>3+</sup> and Y<sub>1.50</sub>Sc<sub>0.50</sub>O<sub>3</sub>:Dy<sup>3+</sup> have been synthesized by a solid state reaction method and their photoluminescence (PL) properties have been investigated. Single-phase and well-crystallized cubic Y<sub>1.50</sub>Sc<sub>0.50</sub>O<sub>3</sub>:Sm<sup>3+</sup> and Y<sub>1.50</sub>Sc<sub>0.50</sub>O<sub>3</sub>:Dy<sup>3+</sup> phosphors are obtained after calcinations at 800 ºC and 900 ºC for 6 h. X-ray diffraction patterns confirm that both phosphors have a cubic phase without secondary phase. According to scanning electron microscope results, the particle size of both phosphors exhibit relatively irregular and their particle size are determinated to be between 0.27 µm–0.70 µm and 0.25 µm–2.04 µm for Y<sub>1.50</sub>Sc<sub>0.50</sub>O<sub>3</sub>:Sm<sup>3+</sup> and Y<sub>1.50</sub>Sc<sub>0.50</sub>O<sub>3</sub>:Dy<sup>3+</sup>, respectively. The PL excitation and emission spectra are recorded for both types of the phosphors. Emission spectra of Y<sub>1.50</sub>Sc<sub>0.50</sub>O<sub>3</sub>:Sm<sup>3+</sup> and Y<sub>1.50</sub>Sc<sub>0.50</sub>O<sub>3</sub>:Dy<sup>3+</sup> are found to be typical for Sm<sup>3+</sup>and Dy<sup>3+</sup>.</p>
