In Figure 2B of our published manuscript, the peak positions were assigned to (111), (200), (220), (221) and (222) reflections of an FCC lattice. But the (221) reflection was mistakenly assigned. Similarly, in Figure 3A (curve at concentration of 0.095%), the (211) reflection was also wrongly assigned. Now we have corrected these mistakes. In addition, we observed (331) and (311) reflections of the same FCC lattice in Figure 2B and Figure 3A (curve at concentration of 0.095%), respectively. The corrected figures are shown here.
Figure 2. (A) Structure factor S(Q) as a function of scattering wave vector Q for a liquid order suspension at 0.026 wt %. The solid line is a theoretical fitting with a HNC closure relation. (B) Bragg scattered intensity, Is as a function of scattering wave vector Q for the microgel crystalline sample at concentration 0.03 wt %. The peak positions were assigned to (111), (200), (220), (222) and (331) reflection from FCC crystals. (C) Bragg scattered intensity, Is as a function of scattering wave vector Q for the microgel crystalline sample at concentration 0.34 wt %. Two sharp coexistence peaks were (111) and (110) reflections of FCC and BCC lattice. The insets of (B) and (C) are the digital images of the microgel colloidal crystals showing iridescence. For all the samples, the pH was kept at 6.2.
Figure 3. (A) Bragg scattered intensity Is measured as a function of Q for the different crystalline suspensions between 0.03 to 0.34 wt %.
