Abstract

The absorption spectrum of Sm(TTA)3(TPPO)2 (TTA:thenoyltrifluoroacetone, TPPO: triphenylphosphine oxide) doped PMMA (polymethyl methacrylate) matrix at room temperature in the spectra range 400-1800 nm was measured. The energy levels are assigned and analyzed in terms of the free-ion Hamiltonian model. Energy levels and reduced matrix elements calculations are carried out using the complete 198 SLJ basis sets for the 4f5 configuration. Judd-Ofelt parameters have been evaluated and used to predict the radiative properties of Sm(TTA)3(TPPO)2 doped PMMA. The evaluation of the radiative properties indicates that the 4G5/2→6H9/2 transition of Sm(TTA)3(TPPO)2 doped PMMA can be considered as an efficient luminescent material.
