摘要：

Some pyrosilicate scintillators such as Ce:Gd2Si2O7 and Ce:Lu2Si2O7 have a good light output, and especially Ce:(Gd,La)(2)Si2O7 has an excellent light output of over 36,000 ph/MeV. In order to search novel scintilators, we have developed a pyrogermanate-based scintillation material (Ce-0.01,Gd-0.90, La-0.09)(2)Ge2O7 using the floating zone method. Although the light output was decreased due to quenching, 5d-4f transition of Ce3+ was observed around 480 nm in photo- and radio-luminescence spectra. This emission wavelength was longer than that of (Ce-0.01,Gcl(0.90),La-0.09)(2)Si2O7 with an emission wavelength of 390 nm. (C) 2013 Elsevier B.V. All rights reserved.
