Details

New scintillation ceramics Lu2O3:Eu3+ has been fabricated

Lu2O3:Eu3+ optical ceramics with relative density of 98±2 % and average grain size of 50 mm has been produced (fig.1). In-line transmittance of Lu2O3:Eu3+ ceramics achieves 41 % @ 611 nm what is comparable to that of hot pressed samples (fig.2). Europium-doped lutetium ceramics provides nearly 3 times the integrated light output of conventional Bi4Ge3O12  scintillator, that is 25000 photons/MeV.
