Scintillation of Sol-Gel derived Lutetium orthophosphate doped with rare earth ions

Characterization and Scintillation properties of Sol - Gel derived Lu 2 SiO 5 : Ln 3 + ( Ln = Ce , Eu , Tb ) powders

In this paper, we report the synthesis, the characterization and the scintillation properties of sol-gel derived Lu 2 SiO 5 (LSO) powders. Ce 3+ , Eu 3+ and Tb 3+ doped LSO powders have been synthesized by an original sol-gel process. The purity of the materials has been checked by X-Ray diffraction, confirming the elaboration of monophasic powders even for doped samples. Finally, the scintilla...

OPTICAL CHARACTERIZATION OF SOL-GEL GLASSES DERIVED FROM Eu COMPLEX-FORMING PRECURSORS

Fabrication of new optical devices based upon the incorporation of rare earth ions via sol-gel method depends on elimination of dopant ion clusters and residual hydroxyl groups from the final material. The optical absorption and/or luminescence properties of luminescent rare earth ions are influenced by the local bonding environment and the distribution of the rare-earth dopants in the matrix. ...

Optical and structural characterization of cerium doped LYSO sol–gel polycrystal films: potential application as scintillator panel for X-ray imaging†

The optical and structural properties of sol–gel prepared polycrystalline films of Cerium doped Lutetium and Yttrium oxyorthosilicates (Ce:LYSO) are investigated by means of optical spectroscopy, XRD diffraction and Raman spectroscopy. The sol–gel samples are compared to commercially available Ce-doped LYSO single crystals, and a detailed study of the emission properties from the different ceri...

Concentration effect on the scintillation properties of Sol-Gel derived LuBO3 doped with Eu3+ and Tb3+

Preparation and Characterization of Reduced Graphene Oxide Doped in Sol-Gel Derived Silica for Application in Electrochemical Double-Layer Capacitors

In this study, a new graphene ceramic composite (GCC) was prepared based on the reduced grapheneoxide (rGO) doped in sol-gel derived silica. The GCC was prepared by dispersing rGO nanosheets intothe sol-gel precursors containing methyl triethoxysilane, methanol and hydrochloric acid solution.During an acid catalyzed hydrolyze reaction and gelation proc...
