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 ETM powder with the same particle size was obtained by the solution suspension layered extraction technique. The main factors such as spatial resolution of the ETM screen, infrared → visible light emission, chemical stability of ETM and uniformity of the coating were obtained by different methods The ETM screen solves the problems of the uniformity of the ETM film and the chemical stability of the device after encapsulation, and proposes a micro-mosaic screen manufacturing technology that takes into account both spatial resolution and infrared up-conversion luminescence brightness Program.
