CL and elemental data (CL-EDX) for sample R47. (a) Backscattered electrons (BSE) image, (b) cathodoluminescence intensity map; the intensity below a normalized value of 0.235 Imax has been filtered out using a mask, (c) barycenter map in the range 880–925 nm, (d) local CL spectra of two regions at intensities, I ≈0.9 Imax and ≈0.3 Imax on the intensity map (square labeled regions 1 and 2 in b), (e) relative concentration map of the K-content (K/K + Na), and (f) intensity ratio map between the two NIR bands (890–910 nm and 960–980 nm). Circled grain shows the variation in IRCL emission within the grain. These images were generated using Matlab (Version: R2016, Url: https://www.mathworks.com/products/matlab.html).
