文摘

White light emission (Sr_0.85Mg_0.14)₃(P_1?xSi_xO₄)₂: Dy³⁺ phosphors applied for white light emitting diodes (LEDs) were synthesized by the solid state reaction process. The phases and luminescence properties of the obtained (Sr_0.85Mg_0.14)₃(P_1?xSi_xO₄)₂: Dy³⁺ phosphors were well characterized. The presented results demonstrate that the (Sr_0.85Mg_0.14)₃(P_1?xSi_xO₄)₂: Dy³⁺ particles emit an intensive white light emission under excitation at 350 nm. Additionally, the effect of Si⁴⁺ incorporation concentration on the luminescence properties of (Sr_0.85Mg_0.14)₃(PO₄)₂: Dy³⁺ was investigated in detail.
