Selenium vacancies induced surface oxygen adsorption and …
2023年5月30日 · X-ray photoelectron spectroscopy (XPS) measurements were taken by a photoelectron spectrometer (Kratos, AxisUltra). Electrical parameters and detector performance were measured by the Primarius PX600 Fs-Pro source/measurement unit.
X-ray Photoelectron Spectroscopy of Selenates La
2021年4月27日 · New selenates La 2 O 2 SeO 4 and Pr 2 O 2 SeO 4, as well as selenite PbSe 4+ O 3 and selenate PbSe 6+ O 4, have been studied by X-ray photoelectron spectroscopy (XPS). The elemental and ionic compositions of new selenates containing Se 6+, La 3+, and Pr 3+ ions have been confirmed on the basis of XPS parameters of the core and valence electrons.
Structure and Photoelectric Properties of PbSe Films Deposited in …
2020年10月9日 · In this study, we make a comprehensive effort to chemically deposit PbSe films with the use of ascorbic acid as an inhibitor of oxidation of selenourea. The goal is to analyze the influence of ascorbic acid on the composition, morphology, and structural and photoelectric properties of lead selenide.
Ligand-surface interactions and surface oxidation of colloidal PbSe ...
2016年2月24日 · In this regard, positron annihilation spectroscopy (PAS) offers unique advantages over XAS, OAS, and XPS, since it combines a high sensitivity to selectively probe surfaces of nanoparticles 14–16 with an established capacity for depth-profiling of films in the range of ∼10 nm to a few μm. 17–19 These unique merits are highly important in ...
Morphological and microstructural evolution of PbSe films …
2017年4月30日 · Lead selenide (PbSe) is a widely known semiconducting material for infrared sensors in the medium wavelength infrared radiation spectral region (1–5 μm) especially for room temperature operation [1], [2].
Air exposure oxidation and photooxidation of solution
2019年12月1日 · According to the X-ray photoelectron spectroscopy (XPS) studies, thin films oxidation accompanied with the formation of PbSO 3 and PbSO 4 compounds on the (100) facets of PbS QDs. Although MAPbI 3 treatment led to the complete passivation of QDs in the air, perovskite shelling partially oxidized to PbO and PbCO 3 compounds.
