Method for realizing X-ray detection and imaging by using organic-inorganic hybrid metal manganese halide

Abstract

The invention discloses a method for realizing X-ray detection and imaging by using an organic-inorganic hybrid metal manganese halide. The method is realized on the basis of the special property that a manganese halide has responsiveness to X-rays, the manganese halide can be used as a raw material to prepare a scintillator by using the characteristic, and the obtained scintillator film does not emit light under the sunlight, and can display a green light-emitting effect after being irradiated by ultraviolet rays or X-rays, so that the scintillator film can be applied to the field of X-ray detection and imaging; The compound also has excellent photophysical properties, emits green light in a solid state, and can be used as a green light-emitting material to be applied to preparation of a white light LED. According to the method disclosed by the invention, the conventional application scene of the organic-inorganic hybrid metal manganese halide is widened, the potential performance of the material is further excavated, and the method has important significance on both theoretical research and practical application.

Description

technical field [0001] The invention belongs to the technical field of photoluminescent materials, and in particular relates to a method for realizing X-ray detection and imaging by utilizing organic-inorganic hybrid metal manganese halides. Background technique [0002] In recent years, X-ray detection and imaging have been widely used in medical diagnosis, environmental monitoring, industrial flaw detection, safety inspection, and astronomical observation, and have also attracted extensive attention and research from researchers. At present, the implementation methods of X-ray detectors can be roughly divided into two types: direct type and indirect type. The former directly absorbs incident X-rays, generates electronic signals through semiconductors or guides chemical signals through thin films, and directly converts X-rays into visible light, which is limited by high cost and low efficiency; the latter uses scintillation The body performs photoconversion of X-rays to re...
