“…It can be seen that for the solution with 1.0 × 10 −3 M, there were not any Raman signals corresponding to vanadium–oxygen species appeared without enhancement. In contrast, the relative strong characteristic Raman spectra can be observed enhanced either by Ag mirror or AuNPs, and the intensities of Raman peaks increased with increasing vanadium concentration from 1.0 × 10 −3 to 1.0 × 10 −2 M. There were many reports of trace analysis of the organic compounds via SERS, [ 25,29 ] but the analysis of inorganic by SERS like this work is novel. The assignments of each Raman peak are summarized in Table 2.…”

“…It is well‐known that surface‐enhanced Raman spectroscopy (SERS) is one of the most sensitive spectroscopic techniques and has been widely used in many fields. [ 16–34 ] However, this sensitive method just has few reports about the detection of the combination state and polymerization degree of inorganic metal‐oxygen ions in solutions. By using conventional laser Raman spectroscopy (LRS), the structures of vanadium‐oxygen species with different polymerization degree have been proposed by comparison with related model compounds like Pb 5 (VO 4 ) 3 Cl and K 2 Zn 2 (V 10 O 28 )·16H 2 O 35 .…”

Vanadium–oxygen species are very harmful to the environment and human health, and also some vanadium–oxygen species have good biological and biomedical effects to human beings. Thus, the study of vanadium–oxygen species is very significant. The types of V–O species are very complex. So far, however, the various structures of V–O species cannot be identified clearly. In this work, the surface‐enhanced Raman spectroscopy (SERS) was used to study vanadium–oxygen species in aqueous solution directly. The SERS spectra with high enhancement factor (EF) and detail information were obtained by the enhancement substrates such as gold nanoparticles (AuNPs), Ag mirror, the Au‐deposited Pt electrodes, and rough Au electrodes. The structures of vanadium‐oxygen species in solutions with different concentration and pH had been well‐characterized firstly by the combination of SERS experiments with density functional theory (DFT) calculations. This work will promote the basic study of the V–O species, and it is also a promotion for the SERS and analytical chemistry.

“…In 2014, based on Ag-decorated Si-nanocone (SiNC) arrays, SERS was used for DMP analysis with an enhancement factor up to 10 12 [ 128 ]. The substrates were synthesized first and immersed in the sample solutions for 3 h at room temperature, followed by washing with deionized water to eliminate physically-adsorbed molecules, and then dried under nitrogen flow.…”

Surface‐enhanced Raman scattering (SERS) substrates utilizing the interparticle nanogaps as hot spots can provide ultrasensitive and geometry‐dependent enhancement factors in analyte detection. Here, we report theoretical and experimental studies on the optical properties of Ag nanoparticles‐decorated Si‐nanocone frustum (NCF) arrays with various geometrical dimensions to enable engineering of the most effective SERS substrate. Our fabrication steps include electron beam lithography, deep reactive‐ion etching, and metallization. In this regard, the effect of geometrical parameters including height, diameter, and slant angle, associated with Si‐NCF arrays, on optical properties and SERS effect are investigated. Results show that the NCF array with larger height and slant angle exhibit higher antireflection property and excellent performance for low‐concentration analyte molecules detection. Furthermore, our results show that the excitation of Mie resonances in NCF arrays leads to formation of near electric field distributions and enhancement of Si Raman lines. It is demonstrated that the strength of Si Raman line follows the trend of the integrated near electric fields in the excitation volume.
