Abstract

The nano-carbons / carbon nano tubes (CNT) have been synthesized by a noble electrochemical route using a nonaqueous bath. We have synthesized the carbon nano tubes (CNT) by making use of the monomer precursor as the potassium iodide (KI) in different molar concentrations. The nano-carbons / CNTs have been investigated electrochemically by using cyclic- voltammetry and current-time transient response. The cyclic voltammetry results show that the potential lower than -1.5 V leads for the intercalation of the potassium precursor in to the graphite sheets. Also performed currenttime transient response results for the periodic oscillations the interval of 70 seconds. Optical absorbance studies result for the semi conducting nature of deposited nano carbons. Photoluminescence (PL) studies indicate luminescent nature of nano carbons in the visible region. X-ray diffraction (XRD) pattern shows close resemblance with the JCPDS data of ($C_{60}$)fullerenes i.e. carbon nanotubes. The investigated surface morphological (STM) study results needle shaped structure or the cylindrical shaped structure of the nano carbons deposited in the ITO substrate.
