FIGURE 9.3
Images from the RT sample; bright field view (A) and Raman map area (B). Arrow points indicate
various components within the sample; RT component (i), 400°C component (ii), 700°C component
(iii), and 1,000°C component (iv). Actual spectra for each arrow (C) are compared with each (Figure

standard (i-iv). 3D surface figures for each component (1-4), corresponding to components
i-iv, are shown to give a phase distribution (C).
