Brief presentation of the institution
Institute of Physics in Tartu University has been founded in 1960 and has now 232 scientists, 82 PhD students and postdocs, 26 technical and administrative staff. The main mission of the institute is application-driven basic research in Materials Science, Laser physics, Plasma physics, Theoretical Physics, Biophysics, Environmental Physics.
The laboratory of laser spectroscopy is specialized on the investigation and functionalization of novel materials using modern optical and spectroscopic techniques. Current research is focused on the development and characterization of applied nanomaterials for optical sensors, photonics and biomarkers (details please see: http://www.fi.tartu.ee/labs/lsl/).
The research group involved in this project has a long-standing experience in:
1. Initiation of different homogeneous pulsed discharges (volume, sliding, barrier discharges and plasma jets) in high-pressure conditions.
2. Nanosecond time-resolved spectroscopic diagnostics in VUV-VIS range as well as imaging techniques with ICCD cameras.
3. Synthesis and analysing of different nanomaterials.
Main Plasma with liquids related topics
-Physico-chemical processes initiated in plasma-liquid interface by low-temperature atmospheric- pressure plasmas.
-Plasma-induced synthesis and surface treatment of nanomaterials in liquids.
Main Plasma with liquids related research techniques and equipment
- Pulsed high-voltage power suppliers for generation of electrical discharges (- 20kV, 1-5000Hz, rise-time 20 ns).
- Fast PMT and nanosecond-gated ICCD cameras with VUV-VIS spectrometers for time-resolved optical emission spectroscopy.
- Measurement systems for data acquisition and processing.
- Analytical characterization of nanomaterials: Scanning Electron Microscopy with EDS for element analysis, Transmission Electron Microscopy, Atomic Force Microscopy, micro-Raman Spectroscopy, analyzing of the size distribution of atmospheric aerosol nanoparticles .
- Chemical analysis of liquid solutions: UV-VIS absorption spectroscopy
Brief information on available facilities related to Plasma with liquids
All described above facilities of characterization techniques for nanomaterials synthesized by plasmas can be accessed on demand.
