Spectroscopy
If the light emitted by an object passes through a prism it is separated into a set of colors. All this colors are indeed a measurement of radiation intensity as a function of wavelength and forms what is known as electromagnetic spectrum. If we regard chemical elements in the periodic table we will find a unique set of colors for each element. These colors are called spectral lines and can be thought as the fingerprint of all the chemical elements found in nature.
Through a spectrometer it is possible to obtain the spectrum of a radiating object for which the identification of spectral lines reveals the chemical elements constituting the object responsible for the emission.
Spectroscopy can be understood as the study of the interaction of light with matter, and it is used at SAOM-Lab to offer services of characterization of materials and processes. Particularly, we can help you to:
- Real-time process monitoring (spectrometer + optical fibers).
- Plasma monitoring during deposition in a sputtering thin film growth.
- Species identification and their stabilization time in sputtering systems.
- Qualitative sample characterization (SEM/EDS).
- Identification of elements or group of elements in a given sample.
- Transmission/Absorption quantification (UV-Vis spectrometer).
- Optical response of thins films grown over transparent substrates.
- Design of spectroscopic systems for the monitoring of processes.
- Technology consulting.
