Ce:CLLB crystal

Ce:CLLB Crystal, has a cubic elpasolite structure with a density of 4.2 g/cm3, emission peak located at 390-420nm, and can be grown by Bridgman method. Ce:CLLB is one of the brightest elpasolite crystals with the light yield at least twice as high as that of CLYC (up to 55,000 ph/MeV). Superior proportionality and high light yield leads the best crystals to the excellent 2.9% energy resolution at 662 keV (approaching Ce:LaBr3) and fast decay time. The selected compositions contain Li ions, Ce:CLLB crystal shows thermal neutron detection efficiency (FOM≥1.5). All these advantages make Ce:CLLB Crystal has a very wide range of applications, such as neutron detection, dual γ/n scanners for security, baggage and cargo screening, oil well logging, et al.

DiHeDral Technology provides high quality Ce:CLLB crystals according to customer's requirements.
