A red borate phosphor Sr3Y1-x(BO3)3: xPr3+ ( 0.01 ≤ x ≤ 0.05 ) was prepared by using a solution combustion reaction method, and its photoluminescence property is investigated. The synthesized phosphors were characterized by X-ray diffraction (XRD), scanned electron microscope (SEM) and photoluminescence (PL).
