Figure 3

(a) Illustration for micro-Raman spectra measurement. (b) Optical image showing the position of laser spot (yellow circle) on the suspended CNTs for micro-Raman spectra measurement. Scale bar, 1 μm. (c) Raman spectra of the same CNT before (the red line) and after (the blue line) deposition of TiO2 NPs.
