EPIDOTE RAMAN PEAK SHIFT AS A FUNCTION OF PRESSURE AND COMPOSITION: CALIBRATION AND PRELIMINARY APPLICATIONSCASTROAdrian E
We found that the surface enhanced Raman spectroscopy of graphene was increased approximately 7-fold by near-fields of plasmonic Ag nanoparticles and the enhancement factor of graphene G peak increased with the particle size. Meanwhile, the LSP resonances of Ag nanoparticles exhibit a 10nm redshift ...

The pump separation of 270 cmn−1nis both much smaller than the Raman peak shift of 440 cmn−1nand much larger than the Raman linewidth of around 100 cmn−1n, which is unfavorable for efficient Raman conversion. Nevertheless, the addition of the pump at 950 nm triples the output power...
The measurements show that this routine can fit the data and find that the value of a Raman peak shift varies within a standard deviation of 0.5 cm−1, which in the wavelength range in question corresponds to ~ 0.02 nm. The spectra of selected minerals are shown in Figs. 7, 8, ...

The Raman peak averaging at 1515 cm−1 is shown to be a significant molecular fingerprint for carotene levels, which can serve as a ripeness indicator in oil palm fruits. Further signal analysis on the Raman peak reveals 4 significant sub bands found to be lycopene (ν1a), β-carotene (...
These four Stokes shifts are obtained with a low peak power of 11 W, and only 3 W are required to obtain three shifts. The Raman gain coefficient for the fiber is estimated to (1.6±0.5)×10(-11) m/W at 1995 nm. The positions and the amplitudes of the Raman peaks are well ...
一、测试了一些样品,得到的是Ramanshift,但是文献是wavenumber,不知道它们之间的转换公式是怎么样的激光波长6328nm。 1 两者是一回事。ramanshift即为拉曼位移或拉曼频移,频率的增加或减小常用波数差表示,拉曼光谱仪得到的谱图横坐标就是波数wavenumber,单位cm-1。
This peak could be attributed to a transition between vibronic states of carbon. In the PL spectra of annealed films, no shift of PL peaks was observed with increasing measurement's temperature (from 6 to 300K). 展开 关键词: Experimental/ annealing carbon nanotubes fullerenes nickel ...
