Based on the FTIR, Raman and XPS results, we propose that Pb2+ and CH3NH3+ surface defects are passivated by R–PO32or R–PO2(OH)while Brsurface defects are passivated by R–NH3+ moieties. This study establishes the combination of PA and APTES ligands as a highly effective dual ...
are calculated to be 2.29 and 2.21 eV, respectively (Supplementary Fig.11b). The detailed energy-level positions of VB edges determined from XPS VB spectra are both 1.06 eV (Supplementary Fig.11e). Thus, the conduction band (CB) potentials of Bi3O4Br and Co–Bi3O4Br-1 are determ...

Also XPS of O element is measured, spectroscopy show that most of O element in film exist as lattice oxygen, another peak in spectroscopy may attribute to defect, absorbed oxygen or oxygen vacancy. Growth of SrMnO3 film establishes foundation for further study of SrMnO3. References [1] ...
uncoordinated Pb2+and Cs+can be effectively passivated by BF4−through formation of ionic bonds. In addition, the bonding relationship between Pb2+(Cs+) and the IIL was also validated by the XPS spectra. As shown in Fig.2b-e, when the IIL was mixed with CsI or PbI2, the binding ...
chemical state, energetic and electronic properties, and photoluminescence (PL) of ZnS QDs were researched by X-ray diffraction (XRD), transmission electron microscope (TEM), X-ray photoelec-tron spectroscopy (XPS), and diffuse reflection and PL spectra combining with first-principles calculations, ...
