Figure 4.

SEM (a) image of bismuth nanomaterials were obtained when the amount of PVP was 0.310 g (sample 3). SEM image (b) and EDX pattern (e) of bismuth nanomaterials were obtained when the amount of PVP was 0.465 g (sample 4). Typical low- (c), high-magnification (d) TEM images, and EDX spectrum (f) of the bismuth nanostructures using DMF instead of EG as solvent (sample 5).
