Optical properties and radiation response of Ce3+‐doped GdScO3 crystals

Abstract 10%‐Ce doped GdScO3 perovskite type single crystal was grown by the Czochralski process. The Ce concentration in the crystal was measured. No impurity phases were observed by powder X‐ray diffraction analysis. We evaluated the optical and radiation properties of the grown crystal. Ce:GdScO3 crystal showed photo‐ and radio‐luminescence peaks due to Ce3+ of 5d‐4f transition and colour centre. The photoluminescence decay time was sub‐ns order. The relative light yield under 5.5 MeV alpha‐ray excitation was calculated to be approximately 9% of BGO. (© 2012 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
