In this work, we investigated the crystal structure and photoluminescence (PL) property of Ca2(Si,P)O4:Eu2+ phosphor doped with Al3+ ions. Changes in the crystal structure were evaluated via X-ray diffraction and X-ray absorption fine structure measurements. With increasing concentrations of Al and P ions, the crystal structure transforms from β to α’L phase. The emission color of phosphor changes from green to blue. However, Al ions exerted only a modest effect on the crystal structure and PL property of the material compared with the absence of Al ions.
