The synthesizing conditions have been optimized in this work. The effect of sintering temperature and boron on the preparation, structure, and photoluminescence were studied by X-ray powder diffraction (XRD), emission, and excitation spectra at room temperature. The red emission is attributed to 1 D 2→3 H 4 transition of Pr3+, and the excited energy comes from the UV absorption of host and transfers to 4f-5d band of Pr3+. Also, the studies include analysis of charge compensation and Pr3+ concentration effects. Compared with conventional solid-state reaction methods, the PBR significantly lowered temperatures of synthesis, shortened reaction time, and enhanced the photoluminescence intensity.
