Yttrium Oxide-Deficient Melts Control Secondary-Phase Distribution in Cerium-Doped Terbium–Yttrium Aluminum Garnet Crystals for White-Light Conversion and X‑ray Imaging
Controlled melt nonstoichiometry was investigated as a processing parameter governing secondary-phase formation and functional properties of Ce3+-doped (Tb,Y)3Al5O12 single crystals grown by micropulling-down. Crystals were grown from melts with 0, 3, 6, 9, and 11 mol % Y2O3 deficiency. X-ray diffraction, electron prob...
