| 摘 要： | 介绍一种YAG荧光屏的结构、制作以及性能。YAG荧光屏不同于传统玻璃荧光屏的一个显著特点就是以具有高热导率、高机械强度、良好绝缘性和透光性的单晶YAG代替玻璃作为荧光屏粉层衬底。我们在YAG衬底上采用离心沉淀法制作荧光粉层；有机膜采用手工旋涂法工艺制作；铝膜采用真空电阻蒸发法制作，并讨论了铝膜的最佳厚度选取。3英寸红、绿、蓝荧光屏在0.5mA电流、29kV电压下亮度分别是6.2×10

| Abstract: | A YAG (Yttrium Aluminum Garnet) phosphor screen is developed by depositing phosphor podwer on a YAG faceplate using a centrifugal sedimentation technique.The fabrication of the phosphor layer,the lacquer layer and the aluminum layer for the YAG phosphor screen are given.Because of the YAG characteristics of higher thermal conductivity than a conventional glass faceplate ,the YAG phosphor screen can obtain the performances of very high luminance,high resolution,good contrast ratio.The luminance of the green,red and blue YAG phosphor screens can reach to 1.4×105 cd/m2，6.2×104 cd/m2 and 8.3×103 cd/m2 at a current of 1.0 mA and an anode voltage of 29 kV respectively,with a half-intensity linewidth of 75μm ,71μm and 96μm respectively,at a cathode current of 0.5 mA. |
