Abstract:In recent years, micro-columnar cesium iodide (CsI) scintillation films remain a highly desirable sensor for digital X-ray imaging due to its superior spatial resolution, bright emission, high absorption efficiency and ready availability. The micro-columnar structure of the CsI scintillation films can reduce the lateral diffusion of scintillation light and greatly constrain the transmission behavior of fluorescence. However, CsI scintillation films exposed to humid air are easily deliquescent and damaged. In t… Show more
