Abstract

Raman and fluorescence spectra of the [Cu(I)Py₂I] and [Cu(I)PyI]₄ complexes are presented. The surface-enhanced Raman (SER) and flourescence spectra from a copper electrode in aqueous iodide solution containing pyridine at two different concentrations are also presented. Comparison of the spectra of the complexes with those of the adsorbed species indicates that the pyridine molecules adsorb on the copper electrode, leading to the formation of surface complexes similar to the [Cu(I)Py₂I] and [Cu(I)PyI]₄ complexes. A model of positively charged metal particles or adatoms is proposed for the SERS “active sites”.

Controllable metal-enhanced fluorescence in organized films and colloidal system

The metal-enhanced fluorescence (MEF) may provide a promising way to address these problems, as it was demonstrated that the optical properties of fluorophores can be modified by adjacent metallic nanostructures [11,12]. Since 1980s when the MEF was confirmed by experiment [13,14], the exploration of fundamental theories and fabrication of functional materials based on MEF have received increasing attentions [15–19]. The interesting MEF phenomenon relates to the unique localized surface plasmon resonance (LSPR) of metal nanoparticles (NPs), which is caused by the collective oscillations of the conduction-band electrons.
In recent years, considerable efforts have been devoted to better understand the unique emission properties of fluorophores enhanced by the localized surface plasmon resonance of metal nanoparticles (NPs), due to the widespread applications of fluorescence techniques. It is demonstrated by experiment and theoretical calculation that the enhancement efficiency strongly depends on the morphology of the metal NPs, the spectral overlap between metal and fluorophores, the separation distance between them, and other factors. Among these aspects to be considered are suitable spacer material and assembling methods to control the spatial arrangement of plasmonic NPs and fluorophore with proper optical properties and interactions. In this contribution, we provide a brief overview on recent progress of metal-enhanced fluorescence in organized films and colloidal systems.
A simple method for fabrication of enhanced fluorescence substrate on TEM copper grid
2013, Optics Communications
Citation Excerpt :
The size and shape of metallic nanostructures have strong impact on the distribution of local EM field and the effect of enhancement [9]. In this regard, many methods have been developed for producing metal substrate with various surface configurations recently, such as the physical polish method, vapor deposition method, and self-assembly of metal colloids method [10–13]. However, the fabricated substrates aforementioned often require a complex process or expensive apparatus, which include vacuum evaporation equipment, novel micro- and nanofabrication systems, precise chemical synthesis process, etc.
A simple method to fabricate enhanced fluorescence substrates was experimentally demonstrated. The fabricated substrate, consisting of silver dendrites, was manufactured by a modified galvanic displacement process between Ag ions and TEM grid at room temperature. Substrate enhancement efficiency, which was evaluated from fluorescence spectrum intensities of the adsorbed Rhodamine 6G (Rh6G) molecules, was found to increase rapidly with reaction time. The observation highlights the importance of strong coupling effects between silver nanobranches and the variation of SEF efficiency can be qualitatively explained with the local surface plasmon resonance model of coupled silver nanostructures. As a result, with a laser, a spectrometer, some second-hand TEM grids, and simple chemical agents, we can easily fabricate the enhanced substrate, which can be applied to study surface enhanced fluorescence, one of the research focuses currently.
Temporal evolution of Raman intensities on surface-enhanced Raman scattering active copper and gold electrodes at negative potentials
1996, Vibrational Spectroscopy
The effect of a roughening procedure on surface-enhanced Raman scattering (SERS) intensity of pyridine at copper and gold electrodes subjected to negative potential has been investigated. Among four procedures tested for a copper electrode the one consisting of electrochemical activation in a solution of LiCl and CuCl₂ resulted in the most stable and effective surface. It was proved that the presence of pyridine during the pretreatment procedure caused a very fast, irreversible decay of SERS intensity for both copper and gold electrodes. Quite stable, at least at room temperatures, gold surfaces were obtained by oxidation-reduction cycles activation in KCl solution.
Effect of molecular oxygen on the surface-enhanced Raman intensity of adsorbed molecules on silver, copper and gold electrodes
1994, Vibrational Spectroscopy
The effect of molecular oxygen (O₂) on the surface-enhanced Raman intensities of pyridine (py) adsorbed on silver, copper and gold electrodes has been investigated. A fast decrease in the SERS intensity with the time of electrode exposure to an electrolyte solution saturated with O₂ has been observed for py adsorbed on silver and copper electrodes. In the case of copper in solutions containing benzotriazole, the decrease in the SERS intensities was not so fast as for py. A less pronounced decrease in the SERS intensity with time of O₂ exposure was observed for py adsorbed on gold electrodes. Part of the SERS intensity of py adsorbed on silver and copper is irreversibly lost after oxygen exposure at open circuit, while the SERS intensity of py adsorbed on gold is totally recovered. The results suggest that O₂ reacts with the SERS-active sites, oxidizing them and precluding the short-range (charge-transfer) mechanism of enhancement from being effective. This oxidation of the SERS-active sites is irreversible for silver and copper, but reversible for gold electrodes.
Effect of hexamethylenetetramine as a corrosion inhibitor for copper in bromide medium
1992, Journal of Electroanalytical Chemistry
The electrochemical behaviour of copper in bromide medium in the absence and presence of hexamethylenetetramine (HMTA) was studied using a rotating disk electrode by several techniques. The results showed that HMTA is a corrosion inhibitor for copper in bromide medium containing FE(III) ion or oxygen as oxidants. Corrosion potential measurements and anodic polarization curves indicated that for [HMTA] < 3.0 × 10⁻³ M, the oxidation mechanism is reversible while the CuBr_n¹⁻ⁿ species are still soluble and it is not affected by the presence of HMTA; for [HMTA] > 3.0 × 10⁻³ M, there is an inhibitive action and the anodic process is not diffusion controlled. The passive film was characterized by fluorescence spectroscope as being a Cu(I)-HMTA-Br⁻ complex.
Ex situ vs. in situ electrode roughening procedures for surface-enhanced Raman spectroscopy
1989, Journal of Electroanalytical Chemistry
Surface-enhanced Raman spectroscopy has been used to probe pyridine, 4-ethylpyridine, and 4-cyanopyridine on silver and gold electrode surfaces. The difference between roughening the electrode in the absence (ex situ) or presence (in situ) of the analyte has been explored. Roughening in situ gives rise to new spectral features attributed to trapping of the analyte in the surface and to complexation of the analyte with metal atoms or ions. It is shown that the ex situ roughening procedure is to be preferred when the orientation or adsorption isotherm of the analyte is of interest.
