摘要

Abstract

New YAG:Yb:Mg and YAG:Yb:Ca:Mg crystals with a short decay time are grown for the first time using the Czochralski method. The pulsed cathodoluminescence spectra of the new scintillators, their light output, and decay time are studied. The light output of the YAG:Yb:Mg and YAG:Yb:Ca:Mg crystals are found to be 460 and 770 photons/MeV, respectively. It is shown that the decay time spectra of the new crystals are described by two components: 1.57/8.5 ns for YAG:Yb:Mg and 1.52/7.79 ns for YAG:Yb:Ca:Mg.
