Notes:
The paper presents two cerium doped lutetium silicate crystals: pyrosilicate Ce:Lu2Si2O7(LPS) and Ce: Lu2(1-x)Y2xSiO5 (LYSO). These two crystals exhibit the expected requirements forgamma detection: high density and high atomic number, high scintillation light yield, good energyresolution and fast response. LPS and LYSO crystals doped with cerium were grown by theCzochralski process. The crystal growth parameters were studied and optimized. Development ofscintillators requires good understanding of the scintillation process. The location within theforbidden band gap of the localized lanthanide energy levels is analyzed by time resolvedspectroscopy and thermoluminescence studies
