The luminescence efficiency of YAG: Ce phosphors

  • Published:
Czechoslovak Journal of Physics B Aims and scope

Abstract

The luminescence intensity of Yttrium aluminium garnet activated by the Ce3+ (YAG∶Ce3+) under cathode-ray excitation depends on the preparation method and content of some dopants. Samples containing Fe, Pt, Ir or some colour centre, respectively, show relatively low luminescence. The maximum luminescence intensity was obtained with the Czochralski method grown single crystals in 98% Ar+2% H2 atmosphere which were sensitized by oxygen annealing followed by treatment at 1500 °C in molybdenum container using a wet hydrogen atmosphere.
