摘要

采用常规固相反应制备了含0.1 ~ 30摩尔%铕(III)和0.1摩尔%钆(III)的K2Bi(PO4)(MoO4):Gd,Eu固溶体。用x射线粉末衍射法、红外光谱和发光光谱对样品进行了表征。结果表明，掺入Eu3+并不影响层状骨架的对称性。在室温下，所有研究样品都表现出强烈的红色光致发光，这与Eu3+离子中的5D0→7F0-4发射跃迁有关。K2Bi(PO4)(MoO4):Gd,Eu作为红色荧光粉具有突出的应用前景。

Luminescence Properties of K2Bi(PO4)(MoO4):Gd,Eu Solid Solutions

Solid solutions K₂Bi(PO₄)(MoO₄):Gd,Eu containing from 0.1 to 30 mole% of europium(III) and 0.1 mole% of gadolinium(III) have been prepared by conventional solid state reaction. The samples are characterized by X-ray powder diffraction method, IR and luminescence spectroscopies. It has been shown that doping with Eu³⁺ does not affect the symmetry of the layered framework. At room temperature, all the studied samples are characterized by intense red photoluminescence, which is associated with ⁵D₀→⁷F_0-4 emission transitions in Eu³⁺ ions. Due to the absence of concentration quenching and color characteristics, K₂Bi(PO₄)(MoO₄):Gd,Eu has prominent prospects for application as a red phosphor.
