“…[25] The UV-vis absorption spectra of the CsPbBr 3 /Cs 4 PbBr 6 particles include two absorption edges, near 345 nm and 525 nm, which are ascribed to Cs 4 PbBr 6 and CsPbBr 3 respectively, [26] further 3b) of the new and aged samples both show a new absorption edge derived from ZnO, near 381 nm. [27] Figure 4 The chemical components of CsPbBr 3 /Cs 4 PbBr 6 /ZnO were futher analyzed by XPS, as shown in Figure S4 (Supporting information). In Figure S4b-c (Supporting information), the peak of Zn 2p 1/2 , Zn 2p 3/2 and O 1s is located at 1043.5 eV, 1020.4 eV, and 530.8 eV, respectively.…”

“…After aging, the diffraction peaks of CsPbBr 3 and Cs 4 PbBr 6 are sharper, indicating that the crystallinity of CsPbBr 3 /Cs 4 PbBr 6 could be improved. Compared to the absorption spectra of CsPbBr 3 /Cs 4 PbBr 6 , the UV-Vis absorption spectra (Figure3b) of the new and aged samples both show a new absorption edge derived from ZnO, near 381 nm [27]. Figure4displays SEM of the aged CsPbBr 3 /Cs 4 PbBr 6 /ZnO (20 mmol/L).…”

“…Zinc oxide has been widely applied as photocatalysts [ 1 , 2 , 3 , 4 ], antimicrobial agents [ 5 , 6 , 7 ], supercapacitors [ 8 , 9 ], sensors [ 6 , 10 ], varistor [ 11 ], biosensors [ 10 ], in solar cells [ 12 , 13 , 14 ], transparent electrodes [ 15 ], and fuel cells [ 9 , 16 ]. This wide range of applications is based on the characteristics of ZnO as an n-type semiconductor, low-cost, chemical, and thermal stability, a direct band gap (~3.3 eV), and binding energy of 60 meV [ 17 , 18 ].…”

“…Various methods are applied to prepare metal oxide nanoparticles and nanocomposites as simple precipitation [ 23 ], electrochemical method [ 24 ], mechanical milling [ 1 ], sol-gel method [ 2 , 25 ], biocombustion [ 26 ], co-precipitation [ 27 ], green synthesis [ 28 , 29 ], sonochemical synthesis [ 30 ] and hydrothermal method [ 31 , 32 ]. The hydrothermal method has many advantages as being simple, low-cost, and low-temperature.…”
