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

Lanthanide-based coordination polymer Dy(1,3,5-BTC)(H2O)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 Dy3+ ions, making the belt-like coordination polymer have potential applications in building minioptoelectronic devices.
