Provider: Ministerstvo školství, mládeže a tělovýchovy
Programme: Mnohostranná vědeckotechnická spolupráce v Podunajském regionu
Implementation period: 01.07.25 - 30.06.27
Workplace:
Fakulta chemicko-technologická - Laboratoř chemie pevných látek
Investigator: Kutálek Petr
Description:
The project unites three research groups from Bulgaria, Czech Republic, and Slovakia, specializing in glassy materials and their behavior under external stimuli. The collaboration combines expertise in glass synthesis (oxide and chalcogenide), thin film deposition, and characterization of phase composition, structure, and optical properties. The project focuses on the synthesis of oxyselenide glasses in bulk and thin film forms, which, despite their challenges in preparation due to differences in melting temperatures of components, offer higher chemical stability, strength, and lower toxicity compared to chalcogenide glasses. Key research activities include: 1. Synthesis of bulk glasses, 2. Deposition of thin films, 3. Characterization and laser-induced modification of structure and morphology, 4. Study of optical properties and changes after irradiation. Advanced methods, such as thermal co-evaporation, will address the challenge of depositing homogeneous multicomponent thin films. The interaction of light with these materials is expected to yield composite materials with chalcogenide (Bi₂Se₃) or oxychalcogenide (Bi₂O₂Se) crystalline phases, enabling applications in optical elements, plasmonics, nanophotonics, and sensors. The project will enhance the participating teams' expertise and lay the groundwork for future international collaborations and EU-funded projects.
