Abstract

The invention provides a scintillator panel and a manufacture method thereof. The manufacture method at least comprises the following steps: first of all, providing a substrate, performing preprocessing on the substrate to enable the substrate to be suitable for a scintillation crystal material to grow thereon; then, growing a pigment-doped Ce3+ halide scintillation crystal material on the substrate; and finally, performing packaging on the surface of the scintillation crystal material. According to the invention, pigment is doped in a Ce3+ halide scintillation crystal material, and the luminous spectrum of the Ce3+ halide scintillation crystal material is converted from an ultraviolet light wave band to a visible light wave band, such that the Ce3+ halide scintillation crystal material can be applied to the field of detection of high-energy radioactive rays. Besides, the scintillator panel provided by the invention is excellent in performance, good in luminescence effect, quite high in energy resolution and quite short in afterglow time, thereby being suitable for industrial production.

Description

technical field [0001] The invention relates to the field of radiation detectors for medical equipment and industrial detection, to a scintillator panel and a manufacturing method thereof, in particular to a scintillator panel with high brightness, high energy resolution and low afterglow and a manufacturing method thereof. Background technique [0002] Fluorescent material is one of the key components in radiation detector diagnostic equipment. It is combined with a photosensitive sensor (such as PMT, amorphous silicon TFT or CMOS sensor) to form a detector, and its performance limits the performance and application of the entire detector; scintillation Body is widely used in various radiation detection fields, specifically designed to high-energy physics, nuclear physics, medical imaging, molecular imaging and other fields. [0003] There are many scintillation crystals widely used at present, and those with excellent performance and wide application mainly include the fol...
