Garnet Crystal Growth in Non-precious Metal Crucibles
The work is motivated by the need for cheap garnet-based scintillators for new high energy physics experiments at colliders and medical equipment. During recent years, garnets became among the most studied scintillators due to a drastic enhancement of light yield achieved in (Lu,Y,Gd)3(Al,Ga)5O12:Ce multicomponent systems. Meanwhile, the production process of YAG- and LuAG-based crystals is easier and less expensive compared to the multicomponent garnets. This work addresses the preparation process and the optical and scintillation properties of YAG, YAG:Ce crystals grown in non-precious metal crucibles.
The work was performed in the frame of Crystal Clear Collaboration and is supported by the Marie Skłodowska-Curie Research, Innovation Staff Exchange Project H2020-MSCA-RISE-2014 No. 644260 “INTELUM”.
