P5+ Ion Doped Gd2SiO5:Ce3+ Scintillation Crystal

Ce 3+ , P 5+ , Ca 2+ , and Zn 2+ ion doped Gd 2 SiO 5 crystals are grown by the Czochralski method. The pulsed cathodoluminescence spectra, light yield, and scintillation time under gamma excitation are studied. It is first shown that additional doping with P 5+ phosphorus ions decreases crystal cra...

Description
Summary:	Ce 3+ , P 5+ , Ca 2+ , and Zn 2+ ion doped Gd 2 SiO 5 crystals are grown by the Czochralski method. The pulsed cathodoluminescence spectra, light yield, and scintillation time under gamma excitation are studied. It is first shown that additional doping with P 5+ phosphorus ions decreases crystal cracking in the fabrication of scintillation elements, and increases the scintillation light yield in comparison with commercial Gd 2 SiO 5 :Ce 3+ crystals.
