Phase diagram of BaI2-LuI3 system and growth of BaI2/LuI3 eutectic scintillator
Original language description
The phase diagram of the BaI2-LuI3 system was created using powder X-ray diffraction (XRD) and differential scanning calorimetry (DSC) analyses. Eutectic scintillating crystal of eutectic composition was grown by the vertical Bridgman method. The results of XRD patterns and DSC curves showed that the phase diagram of the BaI2-LuI3 system had a eutectic point around 77.5 mol% BaI2/22.5 mol% LuI3. No new compound was generated from BaI2 and LuI3 mixture. The 77.5 mol% BaI2/22.5 mol% LuI3 eutectic crystal was composed of BaI2 as rod phase and LuI3 as matrix phase. In addition, the Ce-doped 77.5 mol% BaI2/22.5 mol% LuI3 specimen showed emission peaks originating from 5d–4f transition of Ce3+ ion in the X-ray radioluminescence spectrum and the decay time under γ-ray irradiation was approximately 38 ns.
