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 ...
SPECTRUMSCATTERINGRUTILESPECTROSCOPYSILICONRaman spectra of anatase TiO2 nanocrystals with 2.2-25.5 mu grain sizes were measured at temperature range 83-293 K. The size dependences of the frequency, the bandwidth and the lineshape of the low-frequency mode agree well with those calculated on the ...
UV Raman spectra of these samples indicate that the mixed phases of anatase and rutile coexist in the surface region. Namely, when the TiO2 sample is calcined at 700– 750 oC, the phase junctions between anatase and rutile are derived on the surface of the rutile TiO2, as characterized by ...

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 ...
