Crystalline Intermarriage of Hybrid Organic–Inorganic Halide Perovskite and Epoxide: Enhanced Stability and Modified Optical Properties

“…The N 1s peaks at 402.96 and 401.53 eV represent the N–C and the N–H bonds of the C–NH3 + group of HDAPbI 4 (Figure d), respectively. , After the PO cross-link, a new peak at 286.53 eV ascribed to the C–O bond is generated in the C 1s spectrum, whereas the C–N bond shifts to 285.23 eV (Figure e) . Meanwhile, two N 1s peaks move to 402.12 eV (N–C) and 400.22 eV (N–H) due to the change of N coordination (i.e., C–NH + –C) (Figure f). , Furthermore, there are two main peaks on the O 1s spectrum. The peak at 531.04 eV represents the C–O–C bond, whereas the other at 532.52 eV belongs to the C–O–H bond (Figure S4).…”

A simple process to tune wettability of pectin-modified silanized glass

“…5. in that order [46][47][48]. The C1s binding energies related to C-Si, C-C and C-H chemical environments were simplified by centering the peak at 285.0 eV, as shown in Table 3.…”
