Sep 8, 2023 · In this study, we analyze ZnS CVD transparent ceramic by XPS to study and quantify the bonding states of observable electron shells for Zn and S, along with minor species C and O.

Aug 15, 2003 · Nanocrystalline ZnS thin films were synthesized by chemical vapor deposition (CVD) using Zn (O- i PrXan) 2 [O - i PrXan = S 2 COCH (CH 3) 2] as a single-source precursor compound.

Nov 6, 2012 · Advanced 1 H, 13 C, and 31 P solution- and solid-state NMR studies combined with XPS were used to probe, at the molecular scale, the composition (of the core, the shell, and the interface) and the surface chemistry of InP/ZnS core/shell quantum dots prepared via a non-coordinating solvent strategy.

Nov 20, 2022 · In this study, g-C 3 N 4 /ZnS heterojunction composites were synthesized using zinc acetate (Zn (OAc) 2) and thiourea (Tu) by facile one-pot annealing method.

Apr 5, 2013 · The VBO was measured by two different procedures: an indirect method involving the measurements of the core levels together with the XPS bulk valence band (VB) spectra and a direct method involving the analysis of XPS VB spectra at the interface.

Figure 3 shows the XPS spectra of Zn 2p 3 (a) and S 2p (b) for the deposited ZnS thin films. The signals at binding energy of Zn 2p 3 are corresponding to only Zn-S bond positioned...

Mar 4, 2008 · In this paper, we will report the photoluminescence (PL) and chemical shift of binding energy from Mn 2+ doped ZnS nanocrystals in sol–gel derived hybrid coatings under UV irradiation, and interpret these observations with a photochemical oxidation occurred on the surface of ZnS nanocrystals.

Surface doping through charge transfer with organic species is one of the most effective and widely used approaches to achieve this aim. It usually features easier preparation over other doping...

We report the nonlinear optical (NLO) studies of ZnSnanostructures (NS) in polyvinyl pyrrolidone/dimethyl formamide (PVP/DMF) synthesized by laser ablation technique. We used a frequency doubled...

When using the electron flood gun, the instrument operator should adjust the voltage and the XY position of the electron flood gun to produce peaks from a strong XPS signal (eg O (1s) or C (1s) having the most narrow FWHM and the lowest experimentally measured BE. → …
