Abstract

Rare-earth complex Sm(DBM)₃Phen-doped poly(methyl methacrylate) was synthesized and its absorption and luminescence spectra were studied. The relationship between the coordinate environment of rare-earth ions and the Judd-Ofelt intensity parameter Ω₂ was analyzed and the spectroscopic quality factor, Ω₄/Ω₆, for this material was reported. The oscillator strengths of higher energy levels of Sm³⁺ were predicted, which would be useful to assign the closely spaced multiples at higher energies. The radiative properties for fluorescent levels ⁴G(4)_7/2, ⁴F(3)_3/2 and ⁴G(4)_5/2 of Sm³⁺ were evaluated. The predicted radiative parameters were compared with the observed luminescence spectrum of Sm³⁺ in this system.
