在 77K测定了标题配合物的激发光谱和荧光光谱 ,在配合物的7F0 →5D0 激发光谱里 ,5 80 .1 4nm和 5 80 .6 8nm处呈现两个锐锋 ,说明在该配合物中存在两种Eu3 + 格位 .选择激发配合物的5D0 能级 ,得到两组完全不同的5D0 →7FJ(J=1 ,2 )荧光光谱 ,表明配合物中Eu3 + 离子具有不同的化学环境 ,两种格位的可能点群是C1,C2 或Cs,可能具有与Y2 ( p -CH3 C6H4 COO) 6(C12 H8N2 ) 2 类似的晶体结构 . The excitation and fluorescence spectra of the title complex were determined at 77K. Two sharp peaks appeared at 5 80. 1 4 nm and 5 80. 68 nm in the 7F0 → 5D0 excitation spectrum of the complex, indicating that the complex exists Two kinds of Eu3 + lattice sites were selected to excite the 5D0 energy level of the complex, resulting in two completely different 5D0 → 7FJ (J = 1, 2) fluorescence spectra, indicating that Eu3 + ions in the complex have different chemical environments and two The possible point group of the lattice sites is C1, C2 or Cs, which may have a crystal structure similar to that of Y2 (p -CH3 C6H4 COO) 6 (C12 H8N2) 2.
