A facile solvothermal synthetic route has been developed to prepare CuInTe2 nanowires with the template aiding of anodic aluminum oxide. Microstructure analysis reveals that the as-prepared single crystalline CuInTe2 nanowires have a [112] direction preferential growth. Oriented attachment mechanism has been proposed to explain the anisotropic growth of CuInTe2 nanowires during a polycrystalline-to-single-crystalline transformation process. CuInTe2 nanowires have strong absorption in the visible region based on UV-Vis absorption spectra measurement, confirming its suitability as a light absorbing material in solar cells.
