NaI(Tl) has a very high luminescence (scintillation) efficiency and is available in single crystal or polycrystalline forms in a wide variety of sizes and geometries. The material exhibits no significant self-absorption of the scintillation light. NaI
LYSO scintillation crystal that offers high density and short decay time. It is ideal for applications that require higher throughput, better timing and energy resolution, including time-of-flight PET.
