Histogram show the size distribution of ZnxHg1-xSeyS1-y QDs synthesized at (a) 25, (b) 50, (c) 65, and (d) 80 oC. Each counting was 100 nanoparticles. Other conditions were the same as those described in Figure 3. 2 Figure S2. A linear relationship of the lattice parameter c of the ZnxHg1–xSeyS1–y QDs as a function of Zn mole fractions. 3
