A novel scintillation crystal (Ce 0.01,Gd 0.90,La 0.09) 2Si 2O 7 (Ce:La-GPS) was grown by the floating zone method, and its optical and scintillation properties were investigated. The emission wavelength of this material was 390 nm. Gamma ray excited pulse height and scintillation decay measurement showed that Ce:La-GPS had a high energy resolution (FWHM) of 5% at 662 keV, high light output of 36,000 photons/MeV and fast scintillation decay time of 46 ns.
