“…In fact, the intensity of this binding energy was reduced compared with the present ZnO film (not shown here) which indicates that this binding energy was suppressed by Sn 4þ ion doping. 27) Figure 3(c) shows two strong peaks at 1020.6 eV and 1043.8 eV which correspond with Zn 2p3/2 and Zn 2p1/2 , respectively, consistent with the Zn 2þ ion binding found in previous reports. 28,29) Furthermore, the Sn 3d5/2 and Sn 3d3/2 peaks shown in Fig.…”

Un-doped ZnO and Sn-doped ZnO (SZO) thin films were synthesized using the sol-gel method. The surface morphology of the SZO films showed a large amount of crystallization. Doping with tin dopants not only reduced the surface roughness of the film, but also repaired defects in the pore structure. Notably, the SZO film with a crystallization temperature of 650 C possessed better crystallization and fewer defects when tin dopants were added. XPS analysis confirmed the presence of O-Sn 4þ phases proving the contribution of tin doping on the electrical conductivity of the SZO films. With regards the PL spectra, luminescence in the Zn 2 SnO 4 phase was observed and affected the red-shifted of broad visible emission. In addition, the 9 at% Sn doped ZnO (S 9 ZO) film showed excellent optical transmittance, however the transmittance improved further when the trace of tin dopants (0.4 at%) and 2 at% In were doped in ZnO matrix (I 2 S 0:4 ZO).

“…Thin films of the material are usually grown by radiofrequency magnetron sputtering, [2,13] although some other techniques, each having its own strong points, have also come into use. These techniques include mid-frequency dual magnetron sputtering, [11] bipolar pulsed magnetron sputtering, [14] direct current magnetron sputtering, [15] dual ion beam sputtering, [16] electron beam evaporation, [10] dual ion beam-assisted electron beam evaporation, [17] pulsed laser deposition, [18] atmospheric environment laser deposition, [19] rheotaxial growth and thermal oxidation, [20] spray pyrolysis, [6] ultrasonic spray pyrolysis, [5] sol-gel dip coating, [21] deposition from aqueous solutions, [22] and a variety of versions of CVD, viz., its atmospheric-pressure, [23] low-pressure, [24] ion beam-induced, [25] plasma-enhanced, [26] laser-induced, [27] photo-induced, [28] and atomic layer-controlled [29] variants. Recently, there has been considerable interest in epitaxial SnO 2 thin films.…”

Electrochemical Synthesis of Gold and Protein Gradients on Particle Surfaces

A straightforward, versatile approach to the production of protein gradients on planar and spherical particle surfaces is described. The method is based on the spatially controlled oxidation of thiolated surfaces by Au(III) ions generated via the electrochemical oxidation of a gold electrode in a phosphate-buffered saline solution (10 mM PBS, pH 7.2, 150 mM NaCl). Because the gold electrode is in direct contact with the thiolated surfaces, the released Au(III) ions, which are present as Au(III) chloride complexes, give rise to the formation of a surface gradient of Au(I)-thiolate complexes depending on the local redox potential given by the local Au(III) concentration. As is shown on the basis of the use of X-ray photoelectron spectroscopy and fluorescently labeled proteins, the Au(I)-thiolate complexes can subsequently be functionalized with thiolated proteins, yielding surface density protein gradients on micrometer-sized nonconducting polymer beads as well as linear Au(I)-thiolate gradients on planar silicon surfaces.
