ABSTRACT
Two series of phosphors of Ca8MgSc(PO4)7Dy3+ and Sr8MgSc(PO4)7Dy3+ single-phase white-emitting phosphors with high thermal emission stability are synthesized by the high-temperature solid-state reaction. The crystal structure, photoluminescence (PL), PL excitation (PLE), and thermal PL quenching spectra of Ca8MgSc(PO4)7xDy3+ and Sr8MgSc(PO4)7xDy3+ were investigated and compared in detail. Upon excitation at 387 nm, M8MgSc(PO4)7xDy3+ (M = Ca/Sr) showed white emission centered at 480, 571, 660, and 754 nm. The white-emitting Dy-phosphor Ca8MgSc(PO4)7Dy3+ (CMSPDy) had good terminal stability. The emission intensity of Ca8MgSc(PO4)7Dy3+ still remained 95.2% of that at room temperature at 160 °C, and remained 77.3% at 300 °C under 387 nm excitation.
