Figure 2From: Solvothermal synthesis of uniform bismuth nanospheres using poly(N-vinyl-2-pyrrolidone) as a reducing agent Typical (a) low- and (b) high-magnification TEM images of as-prepared bismuth nanospheres (sample 1). (c) The histogram of size distribution of the bismuth nanospheres prepared from "a". (d) The SAED pattern of a single bismuth nanosphere.Back to article page
