Silicon nanoparticles as Raman scattering enhancers.
In this communication we demonstrate the large amplification values of the Raman signal of organic molecules attached to silicon nanoparticles (SiNPs). Light induced Mie resonances of high refractive index particles generate strong evanescent electromagnetic (EM) fields, thus boosting the Raman signal of species attached to the nanoparticles. The interest of this process is justified by the wid...
متن کاملGold nanoparticles on polarizable surfaces as Raman scattering antennas.
Surface plasmons supported by metal nanoparticles are perturbed by coupling to a surface that is polarizable. Coupling results in enhancement of near fields and may increase the scattering efficiency of radiative modes. In this study, we investigate the Rayleigh and Raman scattering properties of gold nanoparticles functionalized with cyanine deposited on silicon and quartz wafers and on gold t...
متن کاملRaman Scattering and the Continous Wave Silicon
Introduction Scattering of optical radiation by materials is a topic that has received much attention over the past 100 years. One particular type, Raman scattering, was first observed by C.V. Raman in 1928, and since then this inelastic scattering process has found many uses in basic and applied science. Raman scattering can be used to make spectroscopic measurements, or exploited to build Ram...
متن کاملHigh pressure Raman scattering of silicon nanowires.
We study the high pressure response, up to 8 GPa, of silicon nanowires (SiNWs) with ∼ 15 nm diameter, by Raman spectroscopy. The first order Raman peak shows a superlinear trend, more pronounced compared to bulk Si. Combining transmission electron microscopy and Raman measurements we estimate the SiNWs' bulk modulus and the Grüneisen parameters. We detect an increase of Raman linewidth at ∼ 4 G...
متن کاملRaman scattering of alternating nanocrystalline silicon/amorphous silicon multilayers
Nanocrystallite size distribution and structural properties in alternating hydrogenated nanocrystalline silicon/amorphous silicon multilayers were investigated by means of Raman scattering. The obtained Raman spectra show a broad peak at ;480 cm from amorphous Si and some small peaks superposed on the broad peak. According to the positions of the crystallite peak, the mean crystallite size and ...
