摘要/Abstract

摘要： 利用高温固相法合成了Ca₉Gd₂W₄O₂₄: Eu³⁺和Sr₉Gd₂W₄O₂₄: Eu³⁺两个系列四钨酸盐体系以及Ca₃La₂W₂O₁₂: Eu³⁺二钨酸盐体系荧光粉, 对比其荧光性能, 结果发现此三种多钨酸盐荧光粉在395 nm的近紫外和460 nm的蓝光区都有较高的激发强度, 与现有商业化近紫外光、蓝光LED芯片的发射光谱吻合, 可以被这两种LED芯片有效激发, 发射色纯度较高的红光, 是潜在的紫光和蓝光转换型白光LED用红色荧光粉. Eu³⁺离子在Ca₉Gd₂W₄O₂₄和Sr₉Gd₂W₄O₂₄两个四钨酸盐体系中没有浓度猝灭效应, 而在Ca₃La₂W₂O₁₂二钨酸盐体系中的最佳掺杂浓度为40%. 以其中性能优良的Ca₉Eu₂W₄O₂₄、Sr₉Eu₂W₄O₂₄和Ca₃La_1.2Eu_0.8W₂O₁₂结合400 nm发射的紫光InGaN芯片以及460 nm发射的蓝光InGaN芯片制备LED器件, 探讨稀土多钨酸盐红色荧光粉在白光LED中实际应用存在的优点和局限性.

Abstract: Three series of europium(Ⅲ) ion-doped tungstates red phosphors were prepared by the high temperature solid-state reaction method. Their photo-luminescent properties were investigated at room temperature. The results indicate that the phosphors show intensely red emission under 395 and 465 nm light excitation, matching with the light-emitting wavelength of a near-UV-emitting InGaN chip and a blue-emitting InGaN chip, respectively. Therefore the tungstates phosphors can be applied as an efficient red component for NUV InGaN-based and blue InGaN- based white LEDs. No concentration quenching of Eu³⁺ in Ca₉Eu₂W₄O₂₄ and Sr₉Eu₂W₄O₂₄ is observed, while the quenching concentration of Eu³⁺ in Ca₃La₂W₂O₁₂is about 40%. Finally the related LEDs are fabricated with Ca₉Eu₂W₄O₂₄, Sr₉Eu₂W₄O₂₄and Ca₃La_1.2Eu_0.8W₂O₁₂, and the performances of these LEDs are discussed to analyze the advantage and deficiency of such tungstates phosphors in applications for WLEDs.
