The intensity of the peaks increased with increasing annealing temperature. The strong sharp peaks indicate the large quantities and higher degrees of crystallinity of anatase phase of the TNTs. CRS Large Area Scan (LAS) and Depth profiling (DP) were employed to evaluate the crystallinity and phase distribution of TNTs-FS thermally treated at different temperatures. CRS LAS in the XY direction of TNTs-FS revealed the presence of differently crystallized anatase phases of TiO2 with Raman vibrational modes of 159.38 cm-1 (Eg), 208.37 cm-1 (Eg), 399.67 cm-1 (B1g), 514.25 cm-1 (A1g) and 641.58 cm-1 (Eg) for the samples annealed at 350 °C. The effect of annealing temperature on TiO2 phase evolution was meticulously evaluated using CRS for TNTs-FS for the samples annealed at 350 °C, 450 °C, 550 °C and 650 °C. The FWHM was estimated from CRS and decreases with increasing annealing temperature resulting in increasing crystallinity. Increase in anatase FWHM and anatase peak intensity implies higher degree of crystallinity and increasing crystallite sizes were also confirmed by XRD. Growing of titanium dioxide on functional substrates one novel contribution towards the fabrication of efficient electrode materials for solar cell development. Our method of characterizing TNTs-FS from a large area scan along the surface of the samples and depth profiling along the TNTs tube walls using confocal Raman spectroscopy prove to be a pivotal step in the development of efficient photoelectrode materials of the solar devices.]]> Mon 06 Mar 2023 13:37:36 SAST ]]>
