Resonant Raman scattering in Cu2O has been studied at low temperature in the vicinity of its phonon-assisted 1s yellow excitonic absorption edges using a cw continuously tunable dye laser. The multiphonon Raman modes which show resonance enhancement in this region are the following: Γ12-+P (wher...
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 ...

Temperature Dependence of the Raman Spectrum in Anatase TiO2 The frequency and linewidth of the four Raman active modes in anatase have been investigated over the temperature range 20 to 1100 K. The temperature (T) d... T Ohsaka - 《Journal of the Physical Society of Japan》 被引量: 237...
The electronic Raman scattering (ERS) spectrum of the high-temperature superconductor BiSrCaCuOis studied as a function of cation substitution and oxygen content. In unsubstituted crystals with near and above that for the optimal T, the ERS spectra show a redistribution of spectral weight below T...
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, ...
Raman scattering from the Bi2Sr2CaCu2O/sub 8+//sub y/ superconductor The Raman spectrum from 10 to 550 cmhas been obtained from the BiSrCaCuOsuperconductor. Modes similar to those exhibited by YBaCuOare found, as expected from similarities in the crystal structures of the two materials. In ...
