摘　　要：以联吡啶,氯化钌,氯化镧,氯化铒为原料合成了镧、铒共掺杂的探针分子。将探针分子加入到硅溶胶基质中获得了镧、铒共掺杂的压敏漆样品。采用IR,SEM,XPS及荧光发射光谱对探针分子和压敏漆进行了测试分析。红外光谱测试结果表明,探针分子中联吡啶的结构没有被破坏。扫描电镜观察发现探针分子呈花瓣状,XPS测试发现压敏漆中含有Er,La,Ru等元素,说明稀土元素确实被掺入到压敏漆中。紫外吸收光谱表明压敏漆的最佳吸收波段位于200～500 nm处,选择410 nm作为激发光源,压敏漆在590 nm处有很强的荧光发射,并且随着空气压力的增大即氧分子浓度的增加,压敏漆的荧光强度降低,说明压敏漆具有较好的氧猝灭特性。The lanthanum and erbium co-doped probe molecules were synthesized by using bypyridine, ruthenium trichloride, lanthanum chloride and erbium chloride as raw materials. The La, Er co-doped pressure-sensitive paint samples were obtained when the probe molecules were added into the silica matrix. The properties and structure of the pressure-sensitive paint and the probe molecule were analyzed by IR, SEM, XPS and fluorescence emission spectroscopy. IR spectrum results showed that the bipyridine structure of the probe molecules was not destroyed. The scanning electron microscopy showed that the probe molecule was petal-shaped, and the XPS found that Er, La, Ru and other elements were doped in the pressure-sensitive paint. The UV absorption spectra showed that the absorption band of pressure-sensitive paint located at 200 - 500 nm, and the strong fluorescence emission peak was 590 nm when the pressure sensitive paint was excited by 410 nm. The fluorescence intensity of pressure-sensitive paint decreased with oxygen concentration increasing, which indicated that the pressure-sensitive paint had good oxygen quenching characteristics.
