Hunting for the Active Sites of Surface-Enhanced Raman Scattering: A New Strategy Based on Single Silver Particles

Three major findings are reported here.First, a new technique based on lithographic modification with a scanning tunneling microscope (STM) has been developed for fabricating single Ag particles on atomically flat Au(111) surfaces.Second, surface-enhanced Raman scattering (SERS) from one isolated Ag particle has been observed and quantified for the first time.The enhancement factor due to one Ag particle of about 1 μm diameter is on the order of 1E4.This factor includes contributions from all forms of chemical enhancement, which are smaller than 1E2.Finally, strong evidence suggests the importance of clusters containing closely-spaced particles.Extra enhancement due to clusters of randomly distributed Ag particles is around 1E2.We believe that the extra enhancement is spatially localized near the gap sites between two particles in proximity.These gap sites from an important class of SERS-active sites.

Conjugated dyes carrying N, N-dialkylamino and ketone groups: One-component visible light Norrish type II photoinitiators

This work presents new conjugated dyes carrying N, N-dialkylamino and ketone groups for using as one-component Norrish type II visible light photoinitiators. The novel dyes without ketone group were also synthesized to compose two-component visible light photoinitiators for comparisons. The target dyes show the remarkable absorption in visible light region. Photo-differential scanning calorimetry was employed to study visible light photoinitiating polymerization kinetics of methyl methacrylate by new one-component photoinitiators and two-component photoinitiators respectively. The results suggest that the one-component photoinitiators showed much more efficient photoinitiating polymerization of methyl methacrylate than the two-component photoinitiating systems under visible light irradiation. The molecular weight of visible light photopolymer produced by the new photoinitiators was determined. The visible light photoinitiating mechanism of the one-component photoinitiators was studied by absorption and emission spectra, electron spin resonance spectra and cyclic voltammograms analysis.
