摘要：

We synthesized Eu-containing nanoparticles using the ultra-dilute solution method and characterized by FT-IR, NMR, GPC, DSC, and UV-visible absorption/photoluminescence spectra. The size of Eu-containing nanoparticles was 30-150 nm and the nanoparticles were soluble in common organic solvents. A study of the dependence of emission intensities of the Eu-containing nanoparticles on the Eu content showed that the emission intensities increased nearly linearly with increasing Eu content. In addition, no significant emission concentration quenching phenomenon was observed at the Eu content of 0-9.5 mol%. (c) 2006 Elsevier Ltd. All rights reserved.
