Bright-field shadow image

Fig. 14 (a) Shadowed sample of dispersed resin G. The insets are dark-field images. Low-intensity bright-field diffraction contrast images of (b) TE-30 (bottom) and (c) TE-3698 (top), and TE-3170 (bottom). The upper part of b (d) has Pt/C-shadowed TE-30 particles the insets in c are enlargements of some of the particles. All scale bars in a given figure part represent the same scale unless otherwise identified. 

Afterimage - A reverse contrast, shadow image left in the visual field after a direct exposure to a bright light, such as a laser pointer. 

Figure 14a is a typical TEM micrograph of Pt/C shadowed standard-size PTFE dispersion particles, (here sample G) with dark-field images of unshadowed particles in the insets typical BFDC micrographs of several standard-size DuPont dispersion particles are shown in Fig. 14b and c. The dark-field micrographs, taken with 100 reflections, are similar to the bright-held ones except...
