Eu3+ doped heavy germanate scintillating glasses

Eu3+ doped heavy germanate scintillating glasses were prepared by melt quenching method. Their physical and luminescent properties were investigated. The glasses exhibit the densities of more than 6.5 g/cm(3). The transmittance spectra show the glasses have good transmittance in the visible region. The glasses show intense red emissions under 393 nm light excitation and X-ray excitation. The lifetimes of 614 nm emission of Eu3+-doped germanate glasses are in the range from 1.424 ms to 1.484 ms. The results indicate that Eu3+-doped high density germanate scintillating glasses could be of good anti-radiation properties and could be an X-ray scintillating material suitable to X-ray detection for slow event.
