N2 - Some pyrosilicate scintillators such as Ce:Gd2Si 2O7 and Ce:Lu2Si2O7 have a good light output, and especially Ce:(Gd,La)2Si2O 7 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 (Ce0.01,Gd0.90,La0.09) 2Ge2O7 using the floating zone method. Although the light output was decreased due to quenching, 5d-4f transition of Ce 3+ was observed around 480 nm in photo- and radio-luminescence spectra. This emission wavelength was longer than that of (Ce 0.01,Gd0.90,La0.09)2Si 2O7 with an emission wavelength of 390 nm.
