摘　　要：合成并用元素分析、红外光谱法表征了一种4,4′-二甲基-2,2′-联吡啶五氟丙酸钕配合物—Nd(C2F5COO)3·Dmbp(Dmbp:4,4′-二甲基-2,2′-联吡啶).将该配合物溶解在N,N-二甲基甲酰胺中获得了液体介质,依据液体介质的吸收和荧光光谱,通过Judd-Ofelt理论计算获得了钕离子的谱线强度参数(Ω2,Ω4,Ω6)和受激发射截面.计算得到该配合物中钕离子4F3/2→4I11/2跃迁的受激发射截面为5.2×10-20 cm2,表明该钕配合物在液体基质中具有较好的发光特性.通过荧光发射光谱分析可知,Nd(C2F5COO)3·Dmbp将是一种有前途的光学增益材料.A novel neodymium pentafluoropropionate complex, Nd（C2F5COO）Dmbp （Dmbp.. 4,4＇- dimethyl-2,2r-bipyridine）, was synthesized and characterized by elemental analysis, Fourier transform infrared spectra. The optical porperties of the liquid medium which was abtained by dissolving Nd （C2FsCOO）sDmbp in N, N-dimethylformamide was investigated. Based on absorption and luminescence spectra of Nd（C2FsCOO）s Dmbp in DMF, as well as Judd-Ofelt theory, the three intensity parameters and emission cross section were calculated and analyzed The emission cross section of fluorescence transition of Nds＋ ion was and comparable with some laser glasses, which indicated good radiative properties of this neodymium complex in liquid matrix. According to the photolnminescence spectra, Nd （C2FsCOO）3 Dmbp complex will be a promising material for optical gain material in the future.
