Fabrication of size-controllable and luminescent dysprosium benzenetricarboxylate nanobelts at room temperature

摘要

Lanthanide-based coordination polymer Dy(l,3,5-BTC)CH_2O)6 nanobelts were successfully synthesized on a large scale through an extremely simple approach at room temperature; the size of the nanobelts can be easily tuned from several to several hundred micrometers in length, 70-600 nm in width, and 10 -100 nm in thickness by varying concentrations, solvent, and surfactant reasonably. In addition, the as-obtained dysprosium benzenetricarboxylate nanobelts exhibit the characteristic emission of the Dy~(3+) ions, making the belt-like coordination polymer have potential applications in building mini-optoelectronic devices.
