Evaluation of Cerium Doped Lutetium Oxyorthosilicate ( LSO ) Scintillation Crystal for PET
A new scintillation crystal, cerium-doped lutetium oxyorthosilicate &SO) was recently discovered a, with light intensity 75 % of NaI(Tl), scintillation decay time of 12 ns (30%) and 42 ns (70%), effective Z of 66, and density of 7.4 glcc. The fast decay time and scintillation light output of LSO are superior to those of BGO for PET and the stopping power of LSO for 511 keV photons is only sligh...
متن کاملStructural and optical properties of Cerium doped Calcium Fluoride nanoparticles prepared by copercipitation
Calcium fluoride nanoparticles with special amount of cerium ion (%1) were synthesized by coprecipitation. Fourier transforms infrared spectroscopy (FTIR), X-ray diffraction (XRD), absorption and photoluminescence (PL) from CaF2Ce nanoparticles has been investigated. FTIR spectra reveal that there are some amounts of OH, NO3 and other organic functional groups on the parti...

متن کاملPrepration and photoluminescence properties of Ce doped lutetium silicate nanopowders by solegel method
Cerium doped lutetium silicate powders were prepared by solegel process with different cerium concentrations (0, 0.01 and 0.03 mol%). The synthesized lutetium silicate powders were investigated by X-ray diffraction (XRD), TG-DTA, SEM, and Photoluminescence excitation and emissions. The crystallization of lutetium silicate is observed at 1.073 C in S2 (and S3: 1.058 C) sample. The formation of l...
متن کاملEffect of Gamma Irradiation on Optical Properties of Cerium Doped Phosphate Glasses
Transparent bubble free phosphate glasses with composition 50P2O5-10Al2O3-20CaO-(20-x)Na2O-xCeO2 (x varying from 0 to 4 mol %) have been prepared using melt quenching technique. The amorphous nature of the prepared glass samples has been confirmed from XRD spectra. The optical absorption coefficient has been determined from the UVvisible absorption spectra. The prepared glass samples have been ...
