Abstract

The invention discloses a substrate for growing a caesium iodide scintillator. The substrate comprises a substrate body. The upper surface of the substrate body is provided with a smooth leveling layer; the lower surface of the substrate body is provided with an unevenly accidented diffuse reflection layer; and the substrate body is a transparent substrate body. Through such a mode, by using the substrate provided by the invention, the caesium iodide scintillator growing on the substrate can be sealed by use of a common waterproof metal film so that the waterproof sealing cost of the scintillator can be substantially saved, and the production efficiency of the scintillator is improved.

Description

technical field [0001] The invention belongs to the technical field of functional thin film materials, and more specifically, the invention relates to a substrate for growing a cesium iodide scintillator. Background technique [0002] Inorganic scintillator (inorganic scintillator) plays a very important role in radiation detection and is widely used in imaging nuclear medicine, nuclear physics, high energy physics, industrial CT, oil well exploration and safety inspection and other fields. At present, inorganic scintillators are the most researched and applied, among which cesium iodide scintillators with high brightness and high resolution are the most widely used. However, cesium iodide is a hygroscopic material. When it absorbs moisture in the air and deliquesces, the characteristics of the scintillator, especially the image resolution, will be greatly reduced. Therefore, how to effectively package the scintillator is even more important. And different substrates have d...
