Abstract

Cerium-doped lutetium pyrosilicate Lu

∶Ce nanocrystalline was synthesized by the sol-gel method. The structure

morphologies and scintillation properties of Lu

∶Ce nanocrystalline were characterized by X-ray diffractometer (XRD)

scanning electron microscope (SEM)

photoluminescence and X-ray excited luminescence. The results indicate that Lu

∶Ce starts to crystallize at about 1 000 ℃ and the crystallite size increases with the increasing calcining temperature. Well dispersed

homogeneous and near-spherical Lu

∶Ce powder with an average grain size about 28.9 nm was obtained after sintering at 1 200 ℃ for 2 h. The excitation spectrum consists of two intense broad bands at 304 nm and 350 nm

which are corresponding to the 4f5d transition of Ce

ions. The emission peak under 350 nm and X-ray excitation both exhibit a typical asymmetric peak

which are attribute to 5d

5/2

and 5d

7/2

transition of the Ce

ions. The optimized doping concentration of Ce

ion is about 1%. The decay time of the as-prepared Lu

∶Ce phosphor is about 37.2 ns

which can satisfy the requirement of the X-ray detection with high time resolution.
