Synthesis and Luminescence Properties of Eu²⁺-Doped Sr₃MgSi₂O₈ Blue Light-Emitting Phosphor for Application in Near-Ultraviolet Excitable White Light-Emitting Diodes.

ABSTRACT: In this study, [Sr_0.99Eu_0.01]₃MgSi₂O₈ phosphors were sintered at 1200-1400 °C for 1-5 h by using the solid-state reaction method. The crystallinity and morphology of these phosphors were characterized through X-ray diffraction analysis and field-emission scanning electron microscopy, respectively, to determine their luminescence. The photoluminescence properties, including the excitation and emission properties, of the prepared phosphors were investigated through fluorescence spectrophotometry. The α-Sr₂SiO₄, Sr₂MgSi₂O₇, and Sr₃MgSi₂O₈ phases coexisted in the [Sr_0.99Eu_0.01]₃MgSi₂O₈ phosphors, wh
