摘要
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.
