CsI(Tl) Cesium Iodine doping
thallium is the most typical alkali halide scintillation crystal which
wavelength is 550nm, It's best matchable for PD, SiPM etc. CsI(Tl) has high
density, High Z, No cleavage plane, excellent detection effiency, it's
widely used in high energy physics, Nuclear detector, Space detection, security
inspection,SPECT and container checking etc.
