Photoluminescence Property of Lu2Si2O7:Ce3+ Powder for Scintillator Kim, Kyung-Nam; Cao, Guozhong;
In this paper, cerium doped lutetium pyrosilicate (LPS) powders with cerium content (0.05 and 0.07 mol%) were prepared by sol-gel process. The formation of lutetium pyrosilicate (LPS) phase was confirmed by XRD analysis for the powders heated at ; in these powders, a single phase of (LPS) was observed. Cerium doped lutetium pyrosilicate (LPS) powder was agglomerated and constituted of small spherical particles with diameters of about 300 nm. The photoluminescence spectra of the powders showed the characteristic of excitation and there was an emission spectrum for in the host of . The emission spectrum shows a broad band in the range of 350-525 nm; the broad wavelength on the right side of the spectra should be ascribed to the same 5d-4f transitions of , as in the case of cerium doped single crystals.
