【摘要】 用化学络合的方法制得含弱荧光稀土离子镨Pr(III)和铒Er(III)的单体,并经自由基聚合方法制得含Pr(III)和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。更多还原

【Abstract】 The rare-earth-containing monomers were synthesized,and Pr(Ⅲ)-and Er(Ⅲ)-containing polyacrylates were obtained through free-radical copolymerization.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.更多还原
