摘　　要：利用溶液悬浮分层提取技术获得粒度较为一致的电子俘获材料（ＥＴＭ）粉末，考虑ＥＴＭ屏空间分辨率、红外→可见发光亮度、ＥＴＭ化学稳定性和膜层均匀性等主要因素，采用不同方法制作了ＥＴＭ屏，较好地解决了ＥＴＭ膜层均匀性及器件封装后的化学稳定性等问题，并通过测试比较，提出了一种兼顾空间分辨率和红外上转换发光亮度的微镶嵌屏制作技术方案．The powder of electron trapping material (ETM) with the same size was obtained by means of the technique on extracting suspended substance in different layers from the solution of alcohol. According to the major factors on ETM based screen such as space resolution, infrared upconversion luminance, chemical stability and uniformity, a few kinds of ETM based screens were made in different methods. The technique of micro porous filling was put forward by comparing above several kinds of screens.
