Research, Development and Application of Raman Scattering Technology

Dear Colleagues,

Raman scattering, a phenomenon initially uncovered by the pioneering Indian physicist C. V. Raman in 1928, stands as a pivotal milestone in the realm of spectroscopy. Diverging from Rayleigh scattering, Raman scattering manifests as an inelastic scattering process, characterized by frequency shifts that match the vibrational modes and energy levels intrinsic to molecules. Consequently, this phenomenon plays a pivotal role in identifying the chemical bonds and functional groups within a molecule. Spontaneous Raman scattering is a weak process. However, advancements in laser technology and nanotechnology have promoted the excitation efficiency of Raman scattering and led to the development of a series of related new methods, including surface-enhanced Raman spectroscopy, tip-enhanced Raman spectroscopy, resonance Raman spectroscopy, coherent Raman spectroscopy, and spatial offset Raman spectroscopy.

The sensitivity has been pushed down to a single-molecule level and the spatial resolution has reached that of a single chemical bond under ultrahigh vacuum conditions. The extraordinary capabilities of Raman spectroscopy enable its widespread application, including materials analysis, biochemistry, food inspection, environmental monitoring, chemical production, polymers, and geological exploration. We envision that future developments will include the use of single-molecule Raman spectroscopy for general molecules, achieving sub-molecular spatial resolution under ambient conditions and advancing qualitative analysis for an even broader range of applications.

This Special Issue is designed to provide a comprehensive overview of cutting-edge research in the field. We enthusiastically invite researchers to contribute original state-of-the-art articles that push the boundaries of Raman spectroscopy research. Submissions may encompass a broad array of topics, including but not limited to:

• Surface-enhanced and tip-enhanced Raman spectroscopy;
• Coherent Raman spectroscopy;
• Resonance Raman spectroscopy;
• Biological applications of Raman spectroscopy;
• Theoretical and computational advances of Raman spectroscopy;
• Raman sensing;
• Raman optical activity.

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. Photonics is an international peer-reviewed open access monthly 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 2400 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.
