mode was also observed in SER spectrum at lower wavenumbers with expected Stark shifts (Supplementary Fig.3)45. It is worth noting that CO band intensity on Pt in both SEIRAS and SERS changes only slightly (less than 20 and 30%, respectively) in the investigated potential range of 0.6 to ...
However, the absorption spectra of traditional inorganic oxide semiconductors, for example, TiO2, are usually located in the ultraviolet region, so only a small part of the solar spectrum can be used. Forming plasmonic metal-semiconductor nanocomposites can greatly broaden the spectral response range,...
line ω −2Ω corresponding to the coherent two-exciton creation in the Raman spectrum. The induced two-photon emission is not possible in this case. The appearance of the lines on frequencies |ω±2Ω| is possible only if excitons are Bose-condensed. If exciton system is in the norma...
Raman spectrum of the superconductor Bi/sub 2/Sr/sub 2/CaCu/sub 2/O/sub 8/ Two Raman setups, one with high resolution, and the other for spatially resolved (1 x 1 ..mu..m/sup 2/) experiments, have been used to investigate the pola... J Sapriel,L Pierre,D Morin,... - 《Ph...

AES After the gaseous atoms or ions are excited, the outer electrons transfer and radiate the light of different characteristic wavelengths, so the qualitative and quantitative analysis of the elements is realized according to the wavelength and intensity of the characteristic spectrum High precision, ...
A complex Raman spectrum of Cu2O has been measured using the Kr laser line at 6471 , and comparison with the infrared absorption spectrum is made. An F2g Raman active phonon, postulated from symmetry considerations and infrared absorption measurements to lie at either 606 or 181 cm1, could not...
We performed Raman spectroscopy on two different over-doped Bi2Sr2CaCu2O8+x (BSCCO), of which superconducting transition temperatures are 89 K and 77 K. Line-shape analysis of the Raman-spectrum was done, focused on B1g bond buckling mode which have drawn a lot of attention, since ...
Hgba2cacu2o6+deltaPolarized micro-Raman scattering measurements have been performed on the five members of the HgBa2Can-1CunO2n+2+delta(n=1, 2, 3, 4, and 5) high-T-c superconductor family. A systematic evolution of the spectrum, which mainly involves oxygen-related phonons around 590, ...
