Abstract

Rare-earth complex Sm(DBM)(3)Phen-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 Omega(2) was analyzed and the spectroscopic quality factor, Omega(4)/Omega(6), for this material was reported. The oscillator strengths of higher energy levels of Sm(3+) were predicted, which would be useful to assign the closely spaced multiples at higher energies. The radiative properties for fluorescent levels (4)G(4)(7/2), (4)F(3)(3/2) and (4)G(4)(5/2) of Sm(3+) were evaluated. The predicted radiative parameters were compared with the observed luminescence spectrum of Sm(3+) in this system.
