摘要：

The main objective of this work is to present the enhancement of photoluminescence (PL) and structural properties of Ce3+ and Eu3+ co-doped gadolinium orthosilicate Gd2SiO5 (GSO:Eu, Ce) scintillator elaborated by sol-gel method with different concentration of these rare-earth elements. The samples were characterized by X-ray diffraction, field emission-scanning electron microscopy (FE-SEM) and PL spectroscopy. XRD results confirm the crystallization of samples annealed at 1000degree celsius for 4 h to the monoclinic Gd2SiO5 structure. The crystallographic parameters show that Eu3+/Ce3+ incorporated into Gd2SiO5 changes its structure. FE-SEM micrograph results show rod-shaped particles and EDAX spectra confirm the presence of the main constituent elements of the structure. PL showed that two emission peaks dominate the fluorescence spectra of Eu3+ in Gd(2)SiO(5 )and the emission intensity increases relatively with the doping concentration of Ce3+ ions.
