The Al evaporated onto PET presents a complex A12p peak decomposed into Almetal and aloxide component. The ratio Almetal/Aloxide changes with the PET and the temperature of the PET during Al deposition. Transmission electron microscopy (TEM) is performed in order to correlate the morphology and...

XPSAl coordinationAl KLL Auger peakThe chemical state of Al at the surface of dealuminated mordenites has been investigated by X-ray photoelectron spectroscopy. The Al 2p peaks can reasonably be decomposed into two components. The Al KLL Auger transition is more sensitive to the Al coordination,...
X-Ray photoelectron spectroscopic (XPS) analysis of the lanthanum containing gels, heated to 500 and 1000 °C, shows a peak at 836.5 eV for La 3d5/2, which could be due to the presence ofMMOMAl type bridges in the samples.The contribution of m+ in the Ce 3d peaks suggests that both...
High resolution XPS data of the O 1s peak and onset of elastic losses were used to establish the (Al0.14Ga0.86)(2)O-3 bandgap to be 5.0 +/- 0.30 eV. The valence band offsets were -0.25 eV +/- 0.07 eV and 0.05 +/- 0.02 eV for CuI on Ga2O3 or (Al0.14Ga0.86)(2)O-3, ...
A simple approach to estimating the detection limits of X-ray photoelectron spectroscopy (XPS) for any element in any elemental matrix is presented, using the intensity of the background at the expected position for the photoelectron peak to be detected. The approach has been extended to estimate...
The XPS data of Fe 3s spectrum show that the intensity of majority peak decreased with the doping of Al ion and it is associated with the magnetic moment. The XPS analysis of Fe 2p data in conjugation with the Fe 3s data suggests that the Al ions occupy the 2a site of the crystal ...
During a XPS study of oxide growth and segregation on commercial aluminium-silicon alloys, problems were encountered in the application of Cls charge referencing. Using the Cls peak maximum as a reference, shifts were observed in the aluminium and magnesium peak positions, particularly after high ...
XPSOptical band gapHydrothermalIn the present work, well-dispersed structures of spherical-like pure ZnO, Al doped ZnO (AZO) and Al, Sn co-doped ZnO (ATZO) nanocrystals were successfully synthesized by using zinc acetate dihydrate as the starting material and also the low temperature hydrothermal...
This interaction results in color change and surface plasmon resonance (SPR) peak shifted from 410 to 438 nm. The FTIR, HRTEM, XPS, DLS, and zeta potential techniques further confirmed the aggregation of NPs. This method offers a wide linear range from 10 to 0.1 ppm with a detection limit...
