We report a low-energy colloidal synthesis route to homogeneously alloyed Cu-In-Zn-S nanorods that have the wurtzite crystal structure and demonstrate that the optical band gap of these nanorods is compositionally tunable through direct control of the zinc precursor molar ratio. The as-synthesized nanorods are highly monodisperse and can be assembled in both lateral and perpendicular arrays at the liquid-air interface.
