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 scintillation properties of the rare earth doped materials have been studied, the substitution of Ln 3+ (Ln: Ce, Eu or Tb) for Lu 3+ is confirmed, the scintillation yields have been calculated and the afterglow have also been measured, confirming the potentiality of the sol-gel derived LSO.
