Abstract

Spherical-shaped Gd ₂O ₃:Pr ³⁺ phosphor particles were prepared with different concentrations of Pr ³⁺ using the urea homogeneous precipitation method. The resulting Gd ₂O ₃:Pr ³⁺ phosphor particles were characterized by X-ray diffraction, field emission scanning electron microscope, and photoluminescence spectroscopy. The effects of the Pr ³⁺ doping concentration on the luminescent properties of Gd ₂O ₃:Pr ³⁺ phosphors were investigated. Photoluminescence measurements revealed the Gd ₂O ₃:1 % Pr ³⁺ phosphor particles to have the strongest emission. The luminescence properties of Gd ₂O ₃:Pr ³⁺ particles are strongly affected by the phosphor crystallinity and X-ray diffraction measurements confirmed that the crystallinity of Gd ₂O ₃ cubic structure could be enhanced by increasing the firing temperature. The luminescent Gd ₂O ₃:Pr ³⁺ phosphor particles have potential applications in areas, such as optical display systems, lamps and etc.
