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
