Abstract

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 (Ce_0.01,Gd_0.90,La_0.09) 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,Gd_0.90,La_0.09)₂Si ₂O₇ with an emission wavelength of 390 nm.
