含稀土配合物聚苯乙烯发光微球的研究

Study on polystyrene luminescent microspheres containing rare earth complexes

采用细乳液聚合法合成了含Eu(DBM)_3(TPPO)_2的聚苯乙烯荧光微球,通过红外光谱、扫描电镜、荧光分光光度计对荧光微球进行了表征。结果表明,以十二烷基硫酸钠为乳化剂制备的聚苯乙烯荧光微球成球性好,发光强度高。同时,交联剂的使用可明显提高荧光微球的规整度及发光强度。

The polystyrene fluorescent microspheres containing Eu（DBM）3（TPPO）2 was synthesized by miniemulsion polymerization. The polystyrene fluorescent microspheres were characterized by infrared spectra,scanning electron microscope and fluorescence spectrophotometer. The results show that polystyrene fluorescent microspheres using sodium dodecyl sulfate as emulsifying agent have regular spherical shape and high luminous intensity. Moreover,it is also found that the use of the crosslinking agent can obviously improve the regularity and luminous intensity of the polystyrene fluorescent microspheres.
