Abstract

In order to obtain new scintillator with higher effective atomic number, a pyrosilicate crystal with a composition (Ce_0.01, Gd_0.54, La_0.25, Lu_0.20)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%).
