Abstract

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 1,200 °C in these powders, a single phase of Lu₂Si₂O₇ (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 Lu₂Si₂O₇:Ce³⁺ powders showed the characteristic of excitation and there was an emission spectrum for Ce³⁺ in the host of Lu₂Si₂O₇. 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 Ce³⁺, as in the case of cerium doped Lu₂Si₂O₇ single crystals.
