Electronic structure, orbital symmetry transformation, charge transfer, and valence state studies on Fe3+ - substituted CaCu3Ti4O12 quadruple perovskites using X-ray photoelectron spectroscopy

Photocatalytic performance and interaction mechanism of reverse micelle synthesized Cu-TiO2 nanomaterials towards levofloxacin under visible LED light

“…0.5CuT material (Fig. 4c) exhibited binding energy of Cu2p 3/2 level at 932.18 and 933.08 eV related to Cu 1+ from Cu 2 O and at 933.68 eV corresponded to Cu 2+ from CuO [42,43]. However, only the Cu 2+ oxidation state has appeared in the case of 1.0CuT sample and the associated peak is observed at 933.58 eV as shown in Fig.…”

Highly Stable and Efficient Mn2+ Doping Zero-Dimension Cs2ZnxPb1–xCl4 Alloyed Nanorods toward White Electroluminescent Light-Emitting Diodes

“…Intriguingly, the above-mentioned features (peak positions and fwhm) of the alloyed perovskite NCs have few changes when the crystal structure and morphology vary (Figure b,c). According to previous studies, ,− the origin of emissions in alloyed NCs may be attributed to the location state that resulted from the orbital hybridization of the Pb 6p, Pb 6s, and Cl 3p antibonding orbital. The band structure of pure Cs 2 ZnCl 4 and alloyed Cs 2 Zn 0.88 Pb 0.12 Cl 4 and Cs 2 Zn 0.92 Pb 0.08 Cl 4 was computed by performing first-principles calculations based on DFT (Figure S7a–c).…”
