Abstract

Rod-shaped (Lu1-xYbx)3Al5O 12 with x=0.05, 0.15, 0.30 and (Y1-xYbx) AlO3 with x=0.05, 0.10, 0.30 single crystals were grown by the micro-pulling-down method. Edge-defined film-fed growth method was used to prepare (Y0.9Yb0.1)VO4 crystal, while Ca 8(La1.98Yb0.02)(PO4) 6O2 crystal was grown by the Czochralski method. Luminescence of these crystals was studied with main attention paid to the charge transfer emission of Yb3+. Temperature tuned decay times in the time scale of units - tens of nanosecond was measured as a feature possibly interesting for an application in scintillation detectors in positron emission tomography.
