Luminescent properties of optical floating-zone grown YSH:Eu single crystal

A single crystal of europium doped YSH was grown by the optical floating zone method for the first time. The scientists of the Shanghai University grew the crystal with a nominal composition of Hf0.86Y0.13Eu0.01O1.93 under air atmosphere in a vertical double-ellipsoid mirror furnace (SciDre HKZ), equipped with 6500 W Xe arc lamp as heating source. They determined the materials photoluminescence and scintillation properties and brought them into perspective with Lu2O3:Eu.
