“…The Pb 4f and I 3d spectra (see Figures S1a and S1b in the Supporting Information) are characterized by a spin–orbit split doublet, with the Pb 4f 7/2 and I 3d 5/2 peaks at a binding energy (BE) of 138.9 and 619.7 eV, respectively. These BE are consistent with literature estimates for bulk PbI 2 (see, e.g., ref and references therein) and indicate the presence of I – and Pb 2+ species. According to the line shape analysis presented in the Supporting Information, the presence of chemically altered I and Pb species in the as-received samples is unlikely or close to the detection limit of our technique.…”

“…A reasonable hypothesis is that these non-perovskite domains are excess precursor material, either PbI 2 or MAI. The literature shows that PbI 2 forms a hexagonal lattice with the nearest neighbor spacing ranging from 4.5 to 4.6 Å. , The hexagonal structure on the non-perovskite domains was 4.3 Å, consistent with the literature within STM measurement uncertainty. Therefore, PbI 2 is considered to be a viable candidate for the non-perovskite domain.…”

“…The BE values found for the Cl 2p signal of Cl bound to Pb, and the corresponding Br 3d Pb−Br and I 4d Pb−I BEs agree with those found in the literature. 9,37,38 No suitable references could be found for Cd bound to Br and I, but higher binding energies relative to Pb are expected due to the lower electronegativity of Cd. 39 For each of the PbS core-only CQDs, only a single component could be fitted to the XPS spectra in Figure 2, so each halide is bound to Pb only.…”
