目的 制备吡啶二甲酸铕的稀土配合物，将其加入胶版油墨中，并对荧光性能进行检测和分析。方法 以稀土材料Eu盐为主要原料，在一定条件下与2,6-吡啶二甲酸反应形成一种光致发光的稀土配合物，并通过红外光谱和荧光光谱对物质结构进行表征。将合成的稀土配合物添加到白色胶印油墨中，通过印刷适性仪将油墨打印在纸张上。结果 通过荧光检测确定了该物质的主要激发波长为365 nm，发射波长为617 nm；在紫外灯照射下，加入质量分数为3%~4%发光材料的油墨所打印图案的油墨颜色接近于稀土材料的荧光颜色；在D65光源下，该油墨的色度与之前相比变化不大，且可以在加网的条件下完成印刷。结论 稀土发光材料在胶印油墨中发光性稳定，且稀土材料荧光体在油墨中可发光，实现了稀土发光油墨对有机荧光油墨的替代，有利于环境的保护。

The work aims to prepare the rare earth complex of europium pyridine dicarboxylic acid and add it to offset ink to detect and analyze the fluorescence properties. A photoluminescence rare earth complex was formed by the reaction of rare earth material Eu salt with 2,6-pyridine dicarboxylic acid under certain conditions. The structure of the material was characterized by IR and fluorescence spectra. The synthesized rare earth complex was added to the white offset printing ink, and the ink was printed on the paper by printing suitability instrument. Through fluorescence detection, the main excitation wavelength of the substance was determined to be 365 nm and the emission wavelength was 617 nm. Under the irradiation of an ultraviolet lamp, the ink color of the pattern printed by the ink added with the luminescent material with the mass fraction of 3%~4% was close to the fluorescent color of the rare earth material and the chromaticity of the ink did not change much compared with the previous one under D65 light source, and the printing could be completed under the condition of screening. The rare earth luminous materials are stable in offset printing ink, and the rare earth fluorescent materials can emit light in the ink. The substitution of rare earth luminous ink for organic fluorescent ink is realized, which is beneficial to the protection of the environment.
