• K2Nb8O21 nanoribbons
• crystal growth
• molten salt synthesis

Single-crystalline K2Nb8O21 nanoribbons with width of 100-500 nm and thickness of ca. 30 nm, and length up to tens of micron, have been successfully synthesized by simply calcining Nb2O5 powders in molten KCl, and characterized with XRD, SEM, SEM, HRTEM and selected-area electron diffraction technique. The growth direction of the obtained K2Nb8O21 nanoribbons was determined to be the < 1 0 0 > crystallography direction.
