Spectroscopy

Spectroscopy is an important technique in surface technology that is used to characterize materials and surfaces. This method analyzes the light that is reflected, absorbed or emitted by a surface to obtain information about its chemical composition, structure and physical properties.

In surface technology, spectroscopy is used in various forms, including infrared spectroscopy (IR), Raman spectroscopy, UV-vis spectroscopy and X-ray photoelectron spectroscopy (XPS).

- Infrared spectroscopy examines the interaction of materials with infrared light. It can provide information about functional groups and molecular bonds on the surface.

- Raman spectroscopy is based on the scattering of monochromatic light by molecules. It enables the identification of chemical compounds and the investigation of crystal structures on the surface.

- UV-Vis spectroscopy measures the absorption and transmission of ultraviolet and visible light by materials. It is often used to analyze dyes, coatings and optical properties of surfaces.

- X-ray photoelectron spectroscopy (XPS) uses X-rays to remove electrons from the top atomic or molecular layer of a material. It provides information about the chemical composition, oxidation states and surface chemistry of materials.

By using spectroscopy in surface technology, materials can be characterized, processes optimized and quality controls carried out. This technique plays a decisive role in the development of new materials, the production of coatings and surface modifications as well as in the analysis of wear mechanisms and corrosion processes.
