CdWO4 Scintillator Crystal—A monoclinic crystal with high luminous efficiency
CdWO4 single crystal is a monoclinic crystal system with good comprehensive scintillation performance, belonging to wolframite-type structure. Compared with other inorganic scintillation crystals, CdWO4 single crystal has high luminous efficiency, short afterglow time, large X-ray absorption coefficient, strong resistance to radiation damage, high material density, and absence of hygroscopicity. Due to these excellent scintillation properties of CdWO4, it has been widely used in nuclear medicine imaging, security inspection, industrial computer tomography (CT), petroleum logging, high-energy physics and other technical fields, especially in the field of medical X-ray CT, container inspection system has very important applications.
