The Raman spectra of fullerene nanofibers were acquired with different incident laser power densities in order to determine their influence in the peak position of the Ag(2) vibrational mode of the fullerene molecule. A procedure to measure the diameter of the laser beam and the power density under the objective of a Raman microscope is proposed. The uncertainties of the measurement and the spectrometer calibration are also presented.

Abstract
The Raman spectra of fullerene nanofibers were acquired with different incident laser power densities in order to determine their influence in the peak position of the Ag(2) vibrational mode of the fullerene molecule. A procedure to measure the diameter of the laser beam and the power density under the objective of a Raman microscope is proposed. The uncertainties of the measurement and the spectrometer calibration are also presented.File in questo prodotto:
