PIXELIZED SCINTILLATION CRYSTAL FILM, AND PREPARATION METHOD AND APPLICATION THEREOF

摘要

A pixelized scintillation crystal film, and a preparation method and application thereof are disclosed. The pixelized scintillation crystal film comprises: a surface pixelized substrate (1) having a surface formed by pixel unit areas (2) separated from each other and isolation belt areas (3) located between pixel units; and scintillation crystals (5, 6) located on the surface pixelized substrate; wherein the scintillation crystal on the pixel unit areas (2) has a first morphology, at least one isolation belt (4) exists in the isolation belt area (3), and the scintillation crystals (5, 6) on the isolation belt (4) have a morphology different from the first morphology. The pixelized scintillation crystal film prepared by using a surface-induced self-isolation technology can reduce the visible light interference between adjacent pixels, and effectively improve the spatial resolution during film imaging. The film has a simple preparation process and can be easily integrated with an existing optoelectronic detection system to realize digital detection.
