Abstract

The neodymium trifluoroacetate complex was synthesized and characterized by single-crystal X-ray diffraction, elemental and TG analysis, FT-IR spectra, and PL spectra. The optical properties of the liquid medium were studied. From the absorption and luminescence spectra, the Judd-Ofelt parameters of the Nd(CF 3 COO) 3 dissovled in phosphorus oxychloride were obtained. Based on the crystal structure, the effects of crystal field and bond valance properties on three intensity parameters Ω t ( t=2,4,6 ) and emission cross-section were analyzed in detail. The emission cross-section of 4 F 3/2 → 4 I 11/2 fluorescence transition (3.63×10 -20 cm 2 ) of the new neodymium compound was higher than those of other Nd(III) complexes and even comparable with some laser glasses
