Abstract
The construction of scintillating ceramics is of great technological importance for various fundamental ap-plications,including medical diagnostic,security inspection,resource exploration and particle physics.The chief challenge is the facile and scalable synthesis of scintillating ceramics with the desirable combina-tion of pore-free,reliable mechanical properties and excellent scintillating performance.Here we present a pressureless glass crystallization strategy for the construction of scintillating composite with high crys-tallinity.The fabricated scintillating composites are featured by small optical turbidity,excellent mechani-cal properties,and efficient scintillating luminescence with the scintillating light yield of 15,000 pH/MeV and about 2.46 times higher than that of the commercial BGO single crystal.Moreover,the scintillat-ing composite derived radiation detector device is successfully elaborated.The practical application for monitoring gamma ray is demonstrated and the precision of the device is less than that of the tolerable deviation of 30％.Our results suggest an innovative approach for expanding the category of scintillating material candidates,pointing to practical application in the field of radiation detection.
