Figure 4
CsPbBr3 nanocrystals (black circles) alongside orthorhombic fit (Pnma, red line) and cubic fit (, green line). Gdiff = (Gobs − Gcalc) for each fit is plotted in dashed lines offset below the data. The octahedral coordination environment of Pb(II) ions for Pnma and structures are shown in the insets from left to right (Pb = gray, Br = yellow, Cs = purple). |
