(possibly amorphous) and LaVO4 phases formed in the VOx/LaF3 catalysts.The photolumi-nescence characterization showed that the photoelectron-hole pair recombination rate over the VOx/LaF3 catalyst was slower than that over pure V2O5.The UV-vis spectrum of VOx/LaF3 indicates that this material ...
The λmax (397.0 nm) of ZnO-doped Co3O4 nanorods was evaluated with UV/visible spectroscopy (UV/Vis., Lamda-950, Perkin Elmer, Germany; http://www.perkinelmer.com). Fourier-transform infrared spectroscopy (FT-IR spectra) was performed with a spectrophotometer (Spectrum-100 FT-IR) in the...
X-ray photoelectron spectroscopy (XPS) was evaluated. It can be realized from the XPS wide spectrum that the S-2 based nanocomposites contained Ni, Fe, O and C elements as shown in Fig.S3. The C signal could be ascribed to adventitious hydrocarbon. The complete XPS spectrums of the Fe-2...

UV‐Vis spectrum reveals that Biz‐3 contains at least five different compounds absorbing between 210 and 265nn. To determine in which of the SPE peaks the cell inhibitory activity co‐eluted, MCF‐7 cells were induces with different concentrations of the SPE peaks for 1, 3 and 5 days. ...
Fig. 4 illustrates the C8F-doped PANi@HPMC CSS-NP's UV/vis absorption spectrum and the spectrum when exposed to C3H6O gas, respectively. As demonstrated in the figure, an absorption peak attributed to the positively charged excitons contained in the PANi chain was detected at 820 nm. At thi...
Absorption spectra were acquired on a Analytikjena Specord 50 UV-Vis spectrophotometer. The particles were dissolved in methanol, and solution was placed in a quarts cuvettes with 1 cm path length. A Perkin Elmer LS 45 Fluorimeter was used for the photoluminescence of the nanoparticles dissolved...
X-ray diffraction, Raman, UV-Vis-IR diffuse reflectance spectroscopy, and H2 temperature programmed reduction (H2-TPR) were used to charac-terize the as-prepared catalysts. Introduction of Mnx+ into CeO2 lattice dramatically improved the full solar spectrum absorption ability, as well as the ...
Irregular change in λm is noticed in the UV–vis spectrum. The dielectric parameters have been interpreted using the results obtained from spectroscopic studies.doi:10.1016/j.cplett.2015.03.051Arivazhagan, G.Department of Physics, Thiagarajar College, Madurai 625009, Tamilnadu, India;Department ...
