Cesium iodide crystals can be divided into three types based on the dopant, CsI(Tl), CsI(Na) and pure CsI, all of them are colorless transparent cubic crystals. CsI crystals have excellent scintillation properties, meaning they can efficiently convert incident radiation into visible light.
Thallium doped sodium iodide-NaI(Tl), is a classic scintillator for detecting gamma-radiation of intermediate and low energies. It has the greatest light output among all the scintillators and a convenient emission range coinciding with a maximum efficiency of PMT with bialkali photocathodes.
GAGG crystal refers to a type of scintillation crystal made from gadolinium aluminum gallium garnet (Gd3Al2Ga3O12). GAGG crystals are valued for their high light output, fast decay time, and good energy resolution. These properties make them well-suited for detecting and measuring ionizing radiation, such as gamma rays and X-rays.
LaBr3 (Lanthanum Bromide) crystal is a scintillation material used in radiation detection and spectroscopy. It belongs to the family of inorganic scintillators and is composed of lanthanum and bromine atoms. LaBr3 crystals have gained popularity in recent years due to their excellent energy resolution, high light output and fast response time.
