Today, as nanotech continues to develop, materials chemistry is one of the key fields covering topics such as porous materials, metal-organic-framework materials, photocatalysts, magnetic materials, nanobiomaterials, and energy materials for fuel cells and batteries. The development of materials chemistry has made important progress through use of spectroscopic methods, such as UV-VIS-IR, OES, optical absorption spectroscopy, LIBS, XRD, vibrational spectroscopy, Raman/SERS/SERRS, photoluminescence, and photospectrometry/plasmonics, which are often supported by SEM, TEM, and AFM analysis to form the foundations of nanoscience and nanotechnology in recent decades. In addition, many scientists investigate also some special reaction mechanisms using spectroscopic tools.

Therefore, in this special issue, we will invite the submission of original research articles as well as review articles that will focus on the recent spectroscopic investigations in materials chemistry in wide fields. We are particularly interested in articles describing new spectroscopic methods and their applications in materials chemistry fields.

Potential topics include, but are not limited to:

• Spectroscopic characterization in fabrication of materials and chemicals
• Spectroscopic observation in photocatalytic applications
• Chemical sensors, biosensors, nanodevices, photothermal and cancer therapy, and so on
• Applications of plasmonic nanostructures and nanocomposites in photocatalysis, solar cells
• Elucidation of the materials and chemical products by spectroscopic analysis
