Cerium doped Lutetium oxyorthosilicate (LSO) is a well-known scintillator that is widely used for gamma-ray detection in counting mode applications. LSO is typically doped with 0.05 - 0.5% Ce while controlling other impurities at low levels. An investigation of the manner in which various co-dopands may influence the scintillation properties, has begun recently. It was found that some co - dopants,...
Cerium doped lutetium oxyorthosilicate scintillators, such as LYSO, which possess high stopping power, high light output and fast decay time, are promising candidates for use in positron emission tomography. In this paper, the luminescence and nuclear spectroscopic properties of two LYSO samples, used in the NN-PET detectors, are studied. UV-excited emission spectra show that maximum emission spectral...
New high lutetium content Lu1.8Gd0.2SiO5:Ce (LGSO) scintillators with promising physical properties for PET, but also for SPECT and X-ray counting CT applications, have recently been developed. The new crystals have a high density (7.3 g/cc), high light output (>90% of NaI(Tl)), suitable emission wavelength for APD readout (420, 480 nm), and fast decay time that can be adjusted from 34 to 45 ns...
