摘要

The absorption and fluorescence spectra of Pr(DBM)(3)(TPPO)(2) (DBM: dibenzoylmethane, TPPO: triphenylphosphine oxide) containing poly(methyl methacrylate) (PMMA) were measured. The energy levels are assigned and analyzed in terms of the free-ion Hamiltonian model. From the data available in the absorption spectrum, various spectroscopic parameters such as the spherically symmetric part of the free-ion Hamiltonian (E-AVG), Slater-Condon (F-2, F-4, F-6), spin-orbit interaction (zeta), Judd-Ofelt (Omega(2), Omega(4), Omega(6)) parameters and the reduced matrix elements are derived. The radiative properties of Pr(DBM)(3)(TPPO)(2) containing PMMA were also predicted according to the Judd-Ofelt theory. The values of the fluorescence branching ratio and the emission cross section of P-3(0) -> F-3(2) fluorescence transition revealed that Pr(DBM)(3)(TPPO)(2) containing PMMA is an efficient luminescent material.
