一种钒酸盐红色荧光粉材料及其制备方法
摘要：
本发明公开了一种钒酸盐基红色荧光粉材料及其制备方法。该钒酸盐基红色荧光粉材料的化学通式为Sc1-x-y-m-nLnxVO4:Eu3+ySm3+mAl3+n，其中0＜x≤0.5，0.01≤y≤0.15，0≤m≤0.05，0≤n≤0.02，Ln:Sc:V:Eu:Sm:Al=x:(1-x-y-m-n):1:y:m:n，Ln为Y、La、Gd、Lu中的至少一种。原料经混合后研磨、高温焙烧、后处理等工序即得。该钒酸盐基红色荧光粉材料在紫外光及蓝光区域有较强的激发；在紫外光及蓝光的激发下，它能发出亮红光。本发明的工艺流程简单，合成的稀土钒酸盐材料纯度高，发光效果佳。
摘要（英）：

The present invention discloses a vanadate base red phosphor material and a preparation method thereof. The vanadate base red phosphor material has a chemical general formula of Sc1-x-y-m-nLnxVO4:Eu<3+>ySm<3+>mAl<3+>n, wherein x is more than 0 and is less than or equal to 0.5, y is more than or equal to 0.01 and is less than or equal to 0.15, m is more than or equal to 0 and is less than or equal to 0.05, n is more than or equal to 0 and is less than or equal to 0.02, a ratio of Ln to Sc to V to Eu to Sm to Al is x:(1-x-y-m-n):1:y:m:n, and Ln is at least one selected from Y, La, Gd and Lu. Raw materials are subjected to mixing, grinding, high temperature calcination, post-treatment and other processes to obtain the finished product. The vanadate base red phosphor material has strong excitation in ultraviolet and blue light regions, wherein the material can emit bright red light under ultraviolet and blue light excitation. In addition, the process is simple, and the synthesized rear earth vanadate material has characteristics of high purity and good luminescence effect.
