Cc-corrected EFTEM: EFTEM images used to construct the Si L2;3 elemental map by means of the three-window technique in the chromaticand spherical-aberration corrected electron microscope. All images were taken using a 40 eV wide energy window. (a) Pre-edge image centered at an energy loss of 55 eV. (b) Pre-edge image centered at 75 eV. (c) Post-edge image centered at 120 eV. (d) Resulting atomic-resolution elemental map; a standard ‘‘average background subtraction filter’’ was applied. Standard conditions for the NCSI mode were applied in all images

 

STEM micrographs of the glass-ceramic obtained at 600 °C after 60 h (a) and the corresponding HRTEM micrographs (b, c); (d) compositional analysis of an EDXS line scan across two nano-crystals, indicated with a yellow arrow in (a).
