N2 - Pyrosilicate scintillation crystals are expected to be the next generation scintillators, because they have good light output and no hygroscopic nature. In this work, (Ce0.01 Gd0.90 Y0.09)2Si2O7 (Ce:Y-GPS)crystal was grown by the floating zone method. Emission wavelengths of this material were at 360 and 380 nm originated from Ce3+ 5d-4f transition, and these emission peaks were located at shorter wavelength side compared with Ce-doped (Gd, La)2Si2O7 due to the change of the crystal field. Gamma-ray-excited pulse height and scintillation decay measurements showed that Ce:Y-GPS had a light output of 48,000 ± 3000 photons/MeV, FWHM energy resolution of 11.8 ± 0.5% at 662 keV and the decay time components of 42 ± 1 ns (58 ± 2%)and 180 ± 10 ns (42 ± 2%).
