Abstract

In-situ temperature studies of the Raman tangential (G-band) and D modes are reported here on single-walled carbon nanotube engineered paper samples. The expansive temperature range was achieved through a temperature stage coupled with the Raman microprobe. The in-situ arrangement allowed for a large temperature variation while spectral data acquisitions were collected. Changes in the characteristics of the peaks were analyzed using a novel deconvolution and fitting algorithm featuring a pseudo-voigt function for the fitting. Results show the variation of spectral parameters over the temperature range and shows specifically the increase in D/G ratio with laser excitation is unaffected by temperature within the range.
