摘　　要：用反相悬浮聚合方法 ,在超声分散的条件下 ,以氧化还原体系为引发剂、Span体系为乳化剂制备丙烯酸铕以及丙烯酸铕 (镧 )悬浮液。对体系的稳定性及稀土盐的荧光性能等进行了研究 ,讨论了镧离子和铕离子之间的荧光增强作用 。The suspension of europium acrylate and europium (lanthanum) acrylate was prepared by inverse suspension polymerization under ultrasonic dispersion,initialed by redox system and in the presence of emulsifier span-system We studied the system stability and fluorescence performance of rare earth complexes We discussed the fluorescence enhancement character between Eu 3+ and La 3+ and observed the appearance and size of particles by the scanning electron microscope
