N2 - 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 (ζ4f), 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→4I11/2 fluorescence transition are comparable with those shown by glasses used in the solid-state laser applications.
