Abstract

Re³⁺ (Re= Ce³⁺, Tb³⁺) doped and co-doped lutetium oxyorthosilicate Lu₂SiO₅ (LSO) optical films were prepared by Pechini sol-gel method combined with spin-coating technique. The luminescence properties were analyzed by measuring the excitation and emission spectra in the UV. The results indicated that the Ce³⁺ excitation bands in the region from 220 to 360nm attributed to the 4f−5d transition of Ce³⁺. Tb³⁺ excitation bands in the region from 220 to 250nm were due to the 4f−5d transitions of Tb³⁺. The emission spectra showed the characteristic emission of ⁵D₁−²F_J (J=7/2,5/2) transition for Ce³⁺⁵ and D₄→⁷F_J (J = 3, 4, 5, 6) transition for Tb³⁺. Energy transfer from Ce³⁺ to Tb³⁺ was observed and discussed.
