Abstract

In this work, the Nd(III) complex doped PMMA with high stimulated emission cross-section, which is one of the most important parameters for laser design, was presented. The molecular structure of the complex, Nd(TTA)3(TPPO)2 (HTTA: 2-thenoyltrifluoroacetone, TPPO: triphenylphosphine oxide), was characterized by single-crystal X-ray diffraction. From the absorption and luminescence spectra, the Judd-Ofelt parameters (Ω2, Ω4 and Ω6) of the Nd3+ ion in PMMA were obtained and the radiative properties were discussed using Judd-Ofelt theory. The stimulated emission cross-section of the emission band at 1.060 μm is 2.75 × 10-20 cm2, which is higher than that of other Nd(III) complex doped organic systems and even comparable with some laser glasses. On the basis of the experimental data and Judd-Ofelt analysis, the 4F3/2 4I11/2 transition of the Nd3+ ion in PMMA can be considered as a possible laser transition.
