Vítězslav Jarý, Ph.D., the postdoctoral researcher at the Institute of Physics of the Czech Academy of Sciences in Prague, was awarded the prize “Česká hlava” (literal translation “Czech Head”). In particular, Vítězslav Jarý obtained the price of ČEZ group for the excellent PhD thesis in technical sciences.

Recently there has been increasing demand for new materials which can be used for detection of invisible ionizing radiation (X-ray, gamma ray), for example in industry (searching for leakage in materials, looking for new natural resources), medicine (CT, PET scanners), security (security checks at the airport gates), physics (LHC particle accelerator in CERN). At the same time, an intensive search for new materials for tunable white LED solid-state lightings is underway. Those two groups of materials have much in common, though it may not be clear immediately.

In a team led by assoc. prof. Martin Nikl, Ph.D., Vítězslav Jarý has been working in research, development and optimization of those groups of materials. Some of the new materials are produced in the Czech Republic with the participation of Institute of Physics, while other ones are gained through wide collaboration with many international laboratories (Japan, China, France, Italy, USA, …). Nikl's team managed to find a novel, previously not investigated a group of materials (ternary sulfides doped by rare earth ions), which could find usage in both application fields mentioned above. “We were the first in the world to synthesize these compounds with given properties and to provide detail description of their structural, optical and paramagnetic properties”, explains Vítězslav Jarý, who graduated from Nuclear chemistry at Faculty of Nuclear Sciences and Physical Engineering, Czech Technical University in Prague, and who had started to work at the Institute of Physics already during his studies. For this group of materials, four national patents were awarded and 15 papers in the international impacted journals were published. “What I find important to say is that this prize, for which I am really grateful, would never come to me without collaborating with many people, not only from the Institute of Physics. I dare to say that nowadays, scientific work cannot be carried out without multiple partnerships. That is why I would very much like to deeply thank all these people I have ever worked with.
