Abstract

Tb doped gadolinium fluoride nanophosphors embedded in an aluminosilicate glass matrix is reported for X-ray imaging applications. The nanocomposite scintillators were prepared by a melt-quench method followed by annealing. The GdF3:Tb nanophosphors precipitated within the oxide glass matrix during the processing and their luminescence and scintillation properties were investigated.
