Abstract

The absorption spectra of Nd(DBM)₃(TPPO)₂ (DBM=dibenzoylmethane; TPPO=triphenylphosphine oxide) in methyl methacrylate (MMA) and polymethyl methacrylate (PMMA) were measured. Slater-Condon parameters (F₂, F₄, F₆), Lander parameter (ζ_4f), nephelauxetic effect parameters (β, δ) and Judd-Ofelt parameters (Ω₂, Ω₄, Ω₆) were calculated on the basis of the absorption spectra. Analysis of the relationship between the structure of rare-earth complexes and the nephelauxetic effect, Judd-Ofelt parameter Ω₂ was carried out. The radiative properties of Nd(DBM)₃(TPPO)₂ in PMMA were also predicted according to the Judd-Ofelt theory. The values of the radiative lifetime and the emission cross-section of ⁴F _3/2→⁴I_11/2 fluorescence transition are comparable with those shown by glasses used in the solid-state laser applications.
