| 摘 要： | 稀土β二酮的配合物因其具有Antenna效应,发光强度明显增强;而且它的激光性质也被证实1] ,是应用价值极大的配合物.稀土配合物与高分子的复合,获得了兼具二者优良性能的功能材料,有很好的应用前景.通常二者的复合多采用直接掺杂、机械共混和熔融等方法.但由于二者的相容性较差,并且存在着浓度淬灭现象,使获得高稀土含量、分散均匀的聚合物发光材料非常困难.以往,杨柏小组分别采用直接掺杂和原位复合的方法制备了含稀土配合物的光学树脂2 ,3 ] ,但稀土配合物含量受到限制.本文在文献4,5 ]的基础上,采用化学沉淀的方法,制备了30～30 0nmEu…

| Abstract: | Eu(DBM) 3·H 2O nanocrystallites were obtained by the chemical precipitation method.By the elemental analyzer,infrared spectrum,TGA-DSC and TEM,that the construction of nanocrystallines,the thermal properties and size were confirmed,in addition,fluorescence excitation and emission spectrum,ultraviolet absorption spectrums were investigation.Then the nanocrystallines were incorporated into the copolymer system of styrene and methyl acrylic acid,the fluorescence functional polymer nanometer material with high lanthanide content (50、wt%) were obtained.The experiment indicated that Eu(DBM) 3·H 2O nanocrystallines particle sizes were in 30～300、nm,it exhibited europium ion charlatanistic luminescence.The optical resins could provide a relatively stable environment for Eu(DBM) 3·H 2O nanocrystallines. |
