Abstract

In the present work, carbon nanotube was synthesis by pulse laser ablation of graphite target in deionize-water. Fourier Transform Infrared Spectroscopy (FTIR), UV-Visible Spectrophotometer and Transmission electron Microscopy (TEM) were used to study chemical bonding, optical absorption, particle size, structure and morphology of the carbon nanotube. The FTIR absorption peaksat 2092.6 cm-1, 2150 and 1641.3 cm-1is due to the C ≡ C and C = C stretching vibration bondrepresents, which suggest the formation of carbon nanoparticles suspend in this suspension, UV absorption peaks coincide with the electronic transitions corresponding to linear hydrogen – capped polyyne (Cn+1H2), polyynes are important precursor molecular components in the formation of carbon nanotubes. The TEM show the aggregation of the carbon nanoparticles with size ranges from (9.4 – 70.5 nm), the structure and morphology of thenanotube can be observed with diameters (12.5 -25) nm andlength(500 -708.3) nm.
