Tellurium nanorods have been successfully fabricated by template and surfactant‐free electrochemical technique from an aqueous solution at room temperature. The as‐prepared tellurium nanorods were characterized by X‐ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Raman spectrometry, UV‐vis spectroscopy and photoluminescence spectroscopy. Films based on tellurium nanorods were constructed to study the photoresponse and I‐V curves. These photoresponse measurements demonstrate that tellurium nanorods exhibited enhanced conductivity under illumination compared to in the dark measurement.
