Tip-enhanced Raman spectroscopy with silver-coated optical fiber probe in reflection mode for investigating multiwall carbon nanotubes

We propose the quantitative method of evaluating the purity of multiwall carbon nanotubes (MWCNTs) using Raman spectroscopy. High purity MWCNTs were prepared by chemical vapor deposition (CVD) to be used as a reference material with 100% purity. Since the intensity and wavenumber ofD′′-band located at around 1500 cm−1were found to be independent of the excitation wavelength of a laser, the purity of MWCNTs was measured by comparing the intensity ratio ofD′′-band toG-band (ID′′/IG) of the sample with that of a reference material. The established method was verified by testing the mixture of amorphous carbon particles and reference MWCNTs.

In this paper, carbon nanotubes were characterized by several characterization methods such as FESEM (field emission scanning electron microscopy), Raman spectroscopy and fourier transform infrared (FTIR) spectroscopy. FESEM is used to characterize the morphology of carbon nanotubes, the structural is characterize by raman spectroscopy and bonding characteristic is determine by FTIR. The morphology of CNTs is found to be multiwall carbon nanotubes with diameter around 30-50 nm. D-peak was observed at 1341 Cm-1 and G-peak at 1575 Cm-1 based on raman spectroscopy result. The chemical bonding observed at range 2400 - 400 from FTIR spectra. These CNTs will be used for in vitro study in future.
