ABSTRACT:
Hafnium oxide HfO2scintillator compositions are doped with titanium oxide and at least an oxide of a metal selected from the group consisting of Be, Mg, and Li. The scintillator compositions can include sintering aid material such as scandium and/or tin and a rare earth metal and/or boron for improved transparency. The scintillators are characterized by high light output, reduced afterglow, short decay time, and high X-ray stopping power. The scintillators can be used as detector elements in X-ray CT systems.
