Figure 3

The melting temperature of colloidal In, Sn and Bi nanocrystals as a function of nanocrystal diameter.

In addition to data for In, Sn and Bi in polyimide resin matrices (green triangles, blue squares and red circles, respectively), this figure also contains data from our prior work on Bi nanocrystals in an Ag matrix (black circles, ref. 9). The melting temperature and melting temperature uncertainty in this figure represent the endothermic valley minimum location and endothermic valley full width at half maximum in the DSC data, respectively. The dotted curves are experimental data fits using Shi’s melting temperature model that accounts for both nanoparticle size effects and matrix effects [ref. 33].
