摘要：采用电子束蒸发技术在玻璃及单晶硅衬底上制备TiO2薄膜，并分别引入离子束辅助轰击、斜角入射沉积等工艺方法，研究了沉积工艺对薄膜折射率的调控作用。利用X射线衍射（XRD）、X射线光电子能谱（XPS）对薄膜的组织结构、成分含量进行了表征，采用紫外可见光分光光度计测试了薄膜的光谱性能并计算其折射率。结果表明，...
Operando XRD analysis was carried out to study the phase transition during the first lithiation/delithiation process, which was performed in a transmission mode using a STOE diffractometer with a position-sensitive detector and Cu Kα1 radiation with the wavelength (λ) of 1.5406 Å, operating ...
The successful interface between TiO2 and rGO was confirmed by the broadening characteristic of the XRD peak for anatase TiO2, increasing D and G band intensity ratios (ID/IG) of Raman spectra from 1.05 to 1.9, and decreasing intensity of UV–Vis transmittance spectra as the rGO concentration ...
which is the standard peak position of a medium-range ordered structure of phosphorus, whereas the XRD pattern 5o3f .p9u°,re62T.7iO°,2a(nPd-T7i5O.02°; Figure 2) displays the main 2θ , which were assigned to character the (101), istic diffraction peaks at 25.3°, (004)...
The size of the nanocrystals and presence of defects have a profound effect on the Raman peak position, line width, etc. To study the effect of size, defects, and temperature on the position and width of the Raman peak, the E g Raman peak is considered. Figure 5b shows the E g mode...
(b) Lattice spacing (d) estimated from (004) XRD peak as a function of thickness. Inset shows the evolution of (004) XRD peak position with change in film thickness. a function of thickness (Fig. 3(b)). This similarity in the thickness dependence is because the carrier comTpheenc...
The emission peak position of the composite nanocrystals heat-treated to 550 °C had 8 nm red-shift and their emission intensity became stronger compared with that of pure TiO2. The most intense emission appeared in 0.4ZrO2–0.6TiO2, which is about 2.4 times of pure TiO2 nanocrystals....
additional note, the presence of rutile was not observed in the diffraction patterns, despite the prolonged thermal treatment at 750 °C being sufficient for the conversion of anatase into rutile which relative to anatase is the more thermodynamically stable polymorph, as previously seen in XRD ...
S8a). The latter sample shows a low-intensity shoulder on the high binding energy side, which suggests the presence of Ti(III), whereas the main Ti 2p3/2 peak corresponds to Ti(IV). The shape and position of the Ti 2p spectra for all the other samples suggest that the surface is ...
In the XRD pattern of pure g-C3N4, characteristic peaks, centered at ~13.1° and 27.4°, correspond to (100) and (002) of g-C3N4 (JCPDS card No. 87–1526) [24]. Compared with mesoporous TiO2 nanofibers, a characteristic peak of g-C3N4 at ~27.4° can be observed in the TiO2/g-...
