中文摘要：

通过乳液聚合的方法,将具有双键的稀土铕配合物与甲基丙烯酸甲酯单体共聚,得到具有稀土特征荧光的单分散微球。采用红外光谱仪（IR）、扫描电子显微镜（SEM）、X射线粉末衍射仪（XRD）对产物的形貌进行分析,结果表明共聚微球粒径均一性较好;借助同步热分析（STA）研究了产物的热性能,紫外光谱仪（UV）和荧光光谱仪测试了产物的光学性能,结果表明共聚微球具有稀土（Eu^3＋）的特征光学性质,并且通过改变稀土配合物含量,可以改变共聚微球的荧光强度。

英文摘要：

The properties of the emulsion polymerized copolymer microspheres with different contents of Eu（MAA）3phen were obtained. Infrared （IR）, scanning electron microscopy （SEM）, X-ray powder diffraction （XRD） were used to analyze the morphology of the products. The thermal properties of the products were studied by synchronous thermal analysis （STA）, and the optical properties were tested by ultraviolet （UV） and fluorescence spectra. The results showed that the Eu^3＋-co-PMMA copolymer microspheres presented the characteristic fluorescence of rare earth, and the fluorescent intensity was enhanced with the increase content of rare earth complexes, without the occurrence of the concentration quenching phenomenon.
