N2 - The absorption spectra of Nd(DBM)3Phen in MMA solution and PMMA matrix were measured at room temperature within wavelength range of 470-950 nm. From the data available in the absorption spectra, spectroscopic parameters such as Slater-Condon parameters (F2, F4, F6), Lander parameter (ζ4f), nephelauxetic effect parameters (β, b1/2, δ) and Judd-Ofelt parameters (Ω2, Ω4, Ω6) were derived. The relationship between the structure of rare-earth complexes and the nephelauxetic effect, Judd-Ofelt parameter Ω2 was analyzed. The close δ values, oscillator strengths of the hypersensitive transition and nearly similar Ω2 values of Nd(DBM)3Phen in MMA and PMMA indicate that the structure in the vicinity of Nd3+ are very similar. The radiative properties of Nd(DBM)3Phen doped PMMA were predicted with the help of the Judd-Ofelt analysis. 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 being used in the solid state laser applications.
