Figure 5From: Special phase transformation and crystal growth pathways observed in nanoparticles†TEM images of thermally coarsened nanocrystalline ZnS in different environments. (a) Hydrothermal coarsening for 32 h at 225°C. (b) Vacuum coarsening for 2 h at 350°C. "W" indicates the location of wurtzite domains in the predominantly sphalerite particles. For further information on the data of Figs. 5a and 5b, see refs. 50 and 18, respectively.Back to article page
