Lu3Al5O12 (LuAG) doped with Ce 3+ is a promising scintillator material with a high density and a fast response time. The light output under x-ray or γ-ray excitation is however well below the theoretical limit. In this paper the influence of co-doping with Tb is investigated with the aim to increase the light output. For singly doped LuAG (with Ce or Tb)(More)
The optical properties of gadolinium gallium aluminum garnet, Gd3(Ga,Al)5O12, doped with Ce(3+) are investigated as a function of the Ga/Al ratio, aimed at an improved understanding of the energy flow and luminescence quenching in these materials. A decrease of both the crystal field strength and band gap with increasing content of Ga(3+) is observed and(More)
