Csi scintillator structure
WebThe crystal structure of CsI is a cubic crystal system. Its space group is Pm3m. The crystal structure of CsI ... In the case of CsI more scintillation material is in the same volume when it is doped with silver or thallium. Because of that doping can improve the scintillator’s performance. 2. Band Structure and Electronic Density of WebThe CsI-TlI layer is a hygroscopic material that will dissolve by moisture in the air. This will give a rapid deterioration of the scintillator layer. The resolution of the scintillator decreases in time. This hygroscopic property of CsI makes it necessary to protect it against moisture in the air.
