    Abstract: PURPOSE: A halogenide-based red fluorescent substance and its preparation method are provided, to improve the emission luminance by a low voltage electron ray, the stability in high vacuum and the color purity. CONSTITUTION: The halogenide-based red fluorescent substance is represented by Ln1-aOX:Eua, wherein Ln is La, Y or Gd; X is Br, Cl or F; and 0.005

    Abstract translation: 目的:提供一种基于卤化物的红色荧光物质及其制备方法,通过低电压电子射线提高发光亮度,提高高真空度的稳定性和色纯度。 构成:卤化物系红色荧光物质由Ln1-aOX:Eua表示,其中Ln为La,Y或Gd; X是Br,Cl或F; 和0.005 <= a <1.0。 该方法包括以下步骤:向镧系元素(Ln)水溶液中加入尿素水解并过滤并干燥; 并将含卤素(X)的溶液和含铕(Eu)的溶液逐滴地干燥,干燥并在氮气氛下在800-1200℃的温度下烧结所得到的粉末。 优选地,镧系元素(Ln)水溶液的浓度为0.05-1.5mol / L。
