NaI(Tl) crystal

When thallium is added to sodium iodide crystals, the resulting NaI(Tl) emits photons (scintillation) when exposed to ionizing radiation. Therefore, it is widely used in scintillation detectors, traditional nuclear medicine, geophysics, nuclear physics, and environmental measurements. NaI(Tl) is the most widely used scintillation material and has the highest light output.

Properties and applications of CsI(Tl) cesium iodide crystal

Cesium iodide (CsI:Tl) crystal is a scintillation crystal, which uses cesium iodide as the matrix material and is doped with an appropriate concentration of thallium (Tl). This crystal has a colorless and transparent cubic structure. CsI:Tl crystals belong to the halide scintillators and are characterized by high density, high average coefficient, low melting point, and high luminous efficiency.
