中文摘要：

用化学络合的方法制得含弱荧光稀土离子错Pr（Ⅲ）和铒Er（Ⅲ）的单体，并经自由基聚合方法制得含Pr（Ⅲ）Er（Ⅲ）的聚丙烯酸酯聚合物。通过对聚合物薄膜的荧光分析发现，敏化离子La（Ⅲ）、Y（Ⅲ）、Yb（Ⅲ）的引入，使含弱荧光稀土离子镨Pr（Ⅲ）和铒Er（Ⅲ）的聚丙烯酸酯表现出了明显的荧光发射特性，且通过引入这些敏化离子，可实现对上述聚合物的特征荧光发射光谱的调控作用；同时发现敏化离子Yb（Ⅲ）对上述两种聚合物的荧光调控作用都较为明显。

英文摘要：

The rare-earth-containing monomers were synthesized, and Pr（ Ⅲ ）-and Er（ Ⅲ ）-containing polyacrylates were obtained through free-radical copolymerizatioru The tunability of the fluorescence properties of the rare-earth-containing polyacrylates were achieved via incorporation of La（ Ⅲ ）, Yb（ Ⅲ ） and Y（ Ⅲ ） into the polymer systems. In particular, Yb（Ⅲ） showed greater fluorescence enhancement for the polymers compared with La（Ⅲ） and Y（Ⅲ）. This study could offer a method for preparing fluorescent polymer systems with tunable fluorescence properties.
