Chakarvarti] Using polycarbonate track-etch membranes (Whatman), copper telluride (Cu1.75Te) nanowires of diameter 100nm and 50nm have been synthesized electrochemically via template-assisted electrodeposition technique on indium tin oxide (ITO) coated glass from aqueous acidic solution of copper (II) sulphate (CuSO4·5H2O) and tellurium oxide (TeO2) at room temperature (30°C). Scanning electron microscopy (SEM) reveals the morphology of the nanowires having uniform diameter equal to the diameter of the template used. X-ray diffraction (XRD) pattern showed the structure corresponding to the hexagonal structure of copper telluride and single-crystalline. Using UV-visible spectrometry, the optical band gap of copper telluride nanowires was found to be 3.092eV for 100nm and 3.230eV for 50nm diameters. The photoluminescence (PL) studies shows higher intensity and broad spectrum in the blue region (450-475nm) of visible light spectrum.
