Raman spectrum of anatase, TiO2 来自 万方 喜欢 0 阅读量: 530 作者:T Ohsaka,F Izumi,Y Fujiki 摘要: Raman spectra of anatase have been observed in natural and synthetic crystals. Both crystals show the same spectral features. The Raman band occurring at 516 cm−1 at room temperature is ...
Evidently, this spectrum has all the characteristics of an amorphous tungsten oxide (a-WO3), namely all bands are broad and their relative band intensities are characteristic of a-WO3.The band at around 960 cm-1 again can be assigned to the terminal W=O stretching mode, possibly on the sur...

Therefore, it is undoubted that the oxidation of PATP is directly related to the hole decayed from the surface plasmon reso- nance of Ag nanoparticle layer. To get the original spectrum of PATP, it also can be detected on the Ag substrate by the irradiation of 785 nm on lower laser ...

(Fig. 4;Supplementary Table 1;Supplementary Note 1). This kind of selective mode enhancement, along with small shifts in peak position, is typical of chemical enhancement15,18. Due to this PIERS enhancement, it was possible to get an excellent Raman spectrum of DNT at concentrations as low ...
Raman spectrum measurement indicates that: the higher the concentration of R6G, the stronger the Raman intensity, but R6G concentration increase with the enhanced Raman intensity varies nonlinearly; when annealing temperature is 450 degrees C, the average size of silver nanoparticles is about 100 to...
Recently, Ag/TiO2 with the controlled nanostructure has been fabricated to act as self-cleaning SERS substrate due to SERS activity for Raman spectrum detection of organic compounds and meanwhile photocatalysis activity for complete decomposition of the adsorbed compounds [20,21]. The high extinction ...
