Webb10 feb. 2024 · Raman Mapping With Raman mapping, a spectral hypercube is collected, rather than a simple intensity image. This means that a Raman spectrum is taken at each position on the sample in a single file. This is then analysed to produce Raman images. There are several methods, including: Point-by-point mapping WebbThe morphological and chemical composition of the resulting fibre meshes were determined using Scanning Electron Microscopy (SEM), Raman spectroscopy, Raman mapping and Fourier-Transform Infrared Spectroscopy (FT-IR). SEM showed the fibres to have an average diameter increasing from ~1–4 µm as the GO loading increased.
