White-light Phosphorescence from Binary Coordination Polymer Nanoparticles
Materials chemistry and physics(2013)
摘要
Phosphorescent nanoscale coordination polymer nanoparticles (NCPs) were conveniently synthesized by phosphorescent carboxyl-functionalized iridium complexes as a building block and rare earth Y(III) ions as metallic nodes. They reveal to be uniform nanospheres with average diameter around 200 nm. Multi-color emission from blue to orange was obtained by tuning the ratios of two iridium complexes with energy transfer between them. Furthermore, the white-light emission with CIE coordinates of (0.319, 0.388) was performed. (C) 2013 Elsevier B.V. All rights reserved.
