Co-Doping of Cerium and Bismuth into Lead-Free Double Perovskite Cs2AgInCl6 Nanocrystals Results in Improved Photoluminescence Efficiency

“…This further indicates that the surface coordination was greatly improved as a result of incorporation of Ce and Bi co-dopants, especially for uncoordinated Cl – ions that tend to dominate the spectra of undoped double perovskite NCs . The vibrations at 1260 to 900 cm –1 of silicone grease were also suppressed in both 2% Ce-doped and 1% Bi–2% Ce-co-doped Cs 2 AgInCl 6 NCs, which were well passivated by oleic acid and oleylamine …”

“…26 The vibrations at 1260 to 900 cm −1 of silicone grease were also suppressed in both 2% Ce-doped and 1% Bi−2% Ce-co-doped Cs 2 AgInCl 6 NCs, which were well passivated by oleic acid and oleylamine. 27 XPS was employed to study the influence of doping on the lattice coordination of Cs 2 AgInCl 6 NCs while using the C−C peak at 284.8 eV for calibration. Figure 3a shows that the C−O peak of the undoped Cs 2 AgInCl 6 NCs was located at 286.3 eV, while that for 1% Bi-doped, 2% Ce-doped, and 1% Bi−2% Ceco-doped perovskite NCs shifted to lower energies, namely, 286.0, 285.9, and 285.9 eV, respectively.…”

Evaluation of the aging of elastomeric acrylonitrile‐butadiene rubber and ethylene‐propylene‐diene monomer gaskets used to seal plates heat exchanger

“…These are associated with the release agent used in the CS. [ 37,38 ] Although, the strong intensity of these peaks may have interfered the reading of important groups with absorption in close wavenumbers, such as, for example, the COC group (peak assignment between 1000 and 1300 cm −1 ) regarding the oxidative reaction. However, due to the nature of the reaction (thermo‐oxidative) and the increase in hardness of the aged samples (Table 1), it is suggested that the oxidative reactions contributed to the formation of new crosslinks.…”
