Abstract

The invention discloses a 9,10-diphenyl anthracene organic single crystal scintillator and a preparation method and application thereof. The preparation method comprises the following steps: under a protective atmosphere, treating raw materials by adopting a sublimation method to obtain yellow powder and 9,10-diphenyl anthracene micro single crystals; dissolving the yellow powder in p-xylene to prepare a saturated solution at 50-80 DEG C, putting the 9,10-diphenyl anthracene micro single crystals into a mold, putting the mold into the saturated solution and enabling the mold to be filled with the saturated solution, and obtaining the 9,10-diphenyl anthracene organic single crystal scintillator at 50-80 DEG C by adopting a gradient cooling method. The 9,10-diphenyl anthracene organic single crystal scintillator emits light after being irradiated by X-rays, the luminous intensity is linearly changed along with the X-ray dosage, and the 9,10-diphenyl anthracene organic single crystal scintillator can be used for quantitative detection and biological and industrial imaging of the X-rays and has good resolution, short decay time, high response speed and stable cycle performance.

Description

technical field [0001] The invention belongs to the technical field of organic scintillators, and in particular relates to a 9,10-diphenylanthracene organic single crystal scintillator and its preparation method and application. Background technique [0002] Since Roentgen discovered X-rays in 1895, it has created an era of using X-rays to visit the internal structure of objects that cannot be seen by the naked eye. People quickly realized the important role of X-rays in many fields such as medical diagnosis, scientific research and industrial non-destructive testing. Indirect X-ray detectors use scintillators to convert X-rays into visible light, and then use visible light to image objects. This kind of detector can avoid radiation damage caused by direct X-ray irradiation on the detector, and effectively guarantee the life of the detector. It is the most Common X-ray inspection and imaging systems. [0003] Scintillator is the core material in the detector of X-ray detec...
