NaI(Tl) crystal

NaI(T1) crystal scintillators have very high luminous (scintillation) efficiencies and are available in a variety of sizes and geometries, making them widely used scintillators. Under optimal conditions, an average of 1×104 photoelectrons are produced per MeV gamma ray.

Technical specifications

LaBr3(Ce) crystal

LaBr3(Ce) is a transparent scintillator material with excellent energy resolution, fast emission and excellent linearity. It has higher light output and better energy resolution than NaI(T1). For energies close to 1 MeV, about 60% more luminescence than NaI(T1). technical specifications

BGO bismuth germanate crystal

BGO is a high-Z, high-density scintillation material, and BGO is a very efficient absorber of gamma rays. Due to the high Z value of the material, the optical fraction of the gamma-ray absorption is high, so a very good peak-to-total ratio can be observed.
