Lutetium oxyorthosilicate doped cerium powder and films have also been reported to be made by sol-gel processing recently. Other researcher proposed a sol-gel route to lutetium-containing scintillator, but the scintillating phase was embedded in an amorphous matrix and was not clearly identified. A sol-gel processing is a promising candidiate to make Lutetium oxyorthosilicate powders and films, and offer several unique advantages. The molecular precursors are used to control the morphology, and texture the powders and thin films. Moreover, the sol-gel route is used to elaborate materials of different composition in various concentrations, and the sol-gel derived materials are synthesized at lower temperature than the ones elaborated by classical solid state synthesis. In general, the synthesis of Lutetium oxyorthosilicate materials using Czochralski method and the scientillation characteristics has been well studied. However, Lutetium oxyorthosilicate materials have been synthesized rarely using sol-gel method, and the scintillator characteristics are not fully understood. Therefore, when it clarifies the synthesis of Lutetium oxyorthosilicate materials using sol-gel method and scientillator characteristics, it is important to investigate crystal structures with dopant concentrations. In this paper, the characterizatic of sol-gel derived Lutetium oxyorthosilicate powders doped with Ce3+ is reported . |
