Thallium-doped cesium iodide (CsI:Tl) scintillation crystal can be made into various detectors and has good future application prospects.

Thallium-doped cesium iodide (CsI:Tl) scintillation crystal is a colorless and transparent cubic crystal that uses cesium iodide as the matrix material and is doped with an appropriate concentration of thallium (Tl). CsI: Tl scintillation crystal is a halide scintillator. It has the characteristics of high density, high average coefficient, low melting point, and high luminous…
