Special Issue Information

Dear Colleagues,

Raman spectroscopy is a non-destructive chemical analysis technique, which could provide detailed information about the chemical composition, structure, polymorphy, crystallinity and molecular interactions of a sample, whether solid, liquid, gas, gel, slurry or powder. Thus, it has been broadly used in optics, biomedicine, environmental science, materials, catalysis, energy, and so forth. Whether the goal is to collect qualitative or quantitative data, Raman analysis can provide key information quickly and easily.

In addition, surface-enhanced Raman scattering/spectroscopy (SERS) has attracted increasing interest in recent years, both in terms of its fundamental physics/chemistry and applications in many fields. Benefitting from the rapid development of nanomaterials and nanotechnologies, SERS are widely used as a label-free and ultra-high sensitivity detection method in surface analyses, as well as biomolecular and chemical sensing. SERS also play an important role in the in situ characterization of surface catalytic reactions under working conditions, providing important spectral evidence regarding the reaction intermediates produced on catalyst surfaces.

This Special Issue aims to focus on the latest advances in the preparation and applications of Raman Spectra in materials characterization, and applications of nanomaterials and nanostructures. Original research papers, as well as review contributions, are welcome in this issue.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Materials is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

How to fabricate large area controllable surface-enhanced Raman scattering (SERS) active nanostructure substrates has always been one of the important issues in the development of nanostructure devices. In this paper, nano-etching technology and magnetron sputtering technology are combined to prepare nanostructure substrate with evolvable structure, and Ag/TiO2/Ag composites are introduced into the evolvable composite structure. The activity of SERS is further enhanced by the combination of TiO2 and Ag and the electron transfer characteristics of TiO2 itself. Deposition, plasma etching, and transfer are carried out on self-assembled 200 nm polystyrene (PS) colloidal sphere arrays. Due to the shadow effect between colloidal spheres and the size of metal particles introduced by deposition, a series of Ag/TiO2/Ag nanostructure arrays with adjustable nanostructure substrates such as nano-cap (NC), nano cap-star (NCS), and nano particle-disk (NPD) can be obtained. These nanoarrays with rough surfaces and different evolutionary structures can uninterruptedly regulate optical plasmon resonance and reconstruct SERS hotspots over a large range, which has potential application value in surface science, chemical detection, nanometer photonics, and so on.
