    In order to obtain new scintillator with higher effective atomic number, a pyrosilicate crystal with a composition (Ce0.01, Gd0.54, La0.25, Lu0.20)2Si2O7 (Ce:LaLu-GPS) was grown by the floating zone method. Emission wavelengths of this material were at 370 and 390 nm. Gamma-ray-excited pulse height and scintillation decay measurement showed that Ce:LaLu-GPS had a light output of 34,000±2000 photons/MeV, an FWHM energy resolution of 6.9±0.2%, and the decay time components of 59±1 ns (13%) and 570±20 ns (87%).
