Summary, etc. In this research, Eu<sup>3+</sup> activated and Dy<sup>3+</sup>-co-doped Y<sub>2</sub>O<sub>3</sub> based phosphors have been synthesized by solid-state reaction method under open atmosphere. The host lattice is composed of 0.25 moles of Sc<sub>2</sub>O<sub>3</sub> which is added to phosphor composition. Thus, Sc<sup>3+</sup> substitution of Y<sup>3+</sup> ions is implemented to form Y<sub>1.40</sub>Sc<sub>0.50</sub>O<sub>3</sub> host lattice. The thermal analysis (DTA/TG) have been carried out from 50 °C to 1400 °C for preliminary examination of thermal behavior of phosphors during heat treatments. After the heating process, the phase formations are characterized by X-ray diffraction resulted as Y<sub>2</sub>O<sub>3</sub> single phase cubic structure. The effects of Eu<sup>3+</sup> and Dy<sup>3+</sup> dopant ions on the photoluminescence and phase formation properties of the hosts are investigated and determined as Dy<sup>3+</sup>-co-doped phoshor has the reduced excitation/emission intensities as well as decay lifetimes.
