Growth and Scintillation Properties of Directionally Solidified Ce:LaBr<sub>3</sub>/AEBr<sub>2</sub> (AE = Mg, Ca, Sr, Ba) Eutectic System
Ce-doped LaBr<sub>3</sub>/AEBr<sub>2</sub> (AE = Mg, Ca, Sr, Ba) eutectics were grown using the Bridgman–Stockbarger (BS) method in quartz ampoules. The eutectics (AE = Mg and Ca) showed optical transparency like optical fiber bundles. A grown Ce-doped LaBr<sub>3</su...

| description | Ce-doped LaBr<sub>3</sub>/AEBr<sub>2</sub> (AE = Mg, Ca, Sr, Ba) eutectics were grown using the Bridgman–Stockbarger (BS) method in quartz ampoules. The eutectics (AE = Mg and Ca) showed optical transparency like optical fiber bundles. A grown Ce-doped LaBr<sub>3</sub>/MgBr<sub>2</sub> eutectic shows a 355 nm emission ascribed to Ce<sup>3+</sup> 4f-5d transition under X-ray excitation. The smaller the ionic size of AE, the higher the light yield of the sample was. The light yield of Ce:LaBr<sub>3</sub>/MgBr<sub>2</sub> was 34,300 photon/MeV, which is higher than Ce:LYSO standard. Scintillation decay time under 662 keV gamma-ray excitation was 18.8 ns. |
