agents is as high as 55% in borogermanate glass matrix
which ensures the glass density exceeding 6.4 g/cm

.Their optical properties were characterized by transmittance

X-ray excited luminescence (XEL) spectra and luminescence decay curves. The energy transfer of Gd

emission spectra and the mean distances of Gd

-Eu
3+
ion pairs. The optimal concentration of Eu
3+
-activated borogermanate scintillating glass under both ultraviolet and X-ray excitation was also determined. It was found that the covalency property of Eu―O bond increases remarkably with the increased Eu
3+
concentration
which was confirmed by the Judd-Ofelt analysis. Both the temperature-dependent luminescence decay curves and emission spectra of Eu
3+
ions in the temperature regions of 80-470 K finally support the stability of luminescent property of the present Eu
3+
-activated oxyfluoride borogermanate glasses.
