Modulation of optical spectra of thiophene oligomers/polymers in CNTs by electrochemical doping. Raman spectra acquired at varying applied (a) positive and (b) negative voltages. Inset in a shows the enlarged spectra of thiophene band. (c) Normalized intensities for thiophene Raman modes and nanotube G-bands as functions of the applied voltage.
