Hyper-rayleigh Scattering and Surface-enhanced Raman Scattering Studies of Platinum Nanoparticle Suspensions
نویسنده
چکیده
Platinum nanoparticles (ptNPs) in the water are synthesized by nanosecond pulsed laser ablation of a pure platinum plate in the distilled water. Using hyper-Rayleigh scattering (HRS) spectroscopy is observed considerable HRS responses. Pt nanoparticles do not have visible-region plasmon absorption, do not represent clear HRS signals, whereas surprisingly, they exhibit strong surface-enhanced Raman scattering.

Hyper-Rayleigh scattering studies of silver, copper, and platinum nanoparticle suspensions
The optical frequency doubling properties of silver, copper, and platinum nanoparticles in aqueous solution are studied via hyper-Rayleigh scattering (HRS) spectroscopy. Substantial HRS responses are observed for silver and copper particles. The response is attributed to enhancement due to resonance of the nonlinearly scattered light with the particles’ surface plasmon absorption band. Platinum...
متن کاملGold nanoparticle-loaded filter paper: a recyclable dip-catalyst for real-time reaction monitoring by surface enhanced Raman scattering.
We report a robust and recyclable 'dip-catalyst' based on a gold nanoparticle (Au NP)-loaded filter paper composite, prepared by a simple dip-coating process using concentrated Au NP suspensions in toluene. While acting as catalysts, the composites display excellent surface enhanced Raman scattering (SERS) efficiency, allowing the real-time monitoring of chemical reactions.

متن کاملSurface Enhanced Raman Scattering of Crystal Violet with Low Concentrations Using Self-Assembled Silver and Gold-Silver Core-Shell Nanoparticles
The active substrates in surface enhanced Raman scattering (SERS) spectroscopy were prepared through self-assembly of nanoparticles on functionalized glasses. Colloidal silver nanoparticles (Ag NPs) were prepared chemically in two different sizes by reduction of AgNO3 using trisodium citrate and sodium borohydride. Gold–silver core–shell nanoparticles were also prepared to compare between the o...
متن کاملNonresonant hyper-Raman and hyper-Rayleigh scattering in benzene and pyridine
Nonresonant hyper-Raman and hyper-Rayleigh spectra excited at 1064 nm are reported for neat benzene and pyridine. The theory of Herzberg-Teller vibronic coupling in nonresonant and preresonant hyper-Raman scattering is developed. Nonresonant hyper-Raman scattering is shown to be vibronically induced by modes that efficiently couple strongly allowed onephoton and two-photon transitions. A weak a...
