SEMINAR ABSTRACT:Properties of materials can be tailored by using ultrafast and highly intense laser sources that opens routes towards the design of nanocomposite devices. Among several techniques, femtosecond laser modification, considered a maskless patterning process, presents numerous advantages over the usual techniques and offers rapid patterning at sub-micrometer resolutions, with flexibility, ease of use, and cost effectiveness. One the most attractive material for such laser modifications is glass, containing photosensitive agents such noble metals. Glass interactions with highly intense laser pulse leads to spatially selected precipitation of metal nanoclusters or nanoparticles which exhibit unique spectral and nonlinear properties which in turn can be utilized for plasmonics and 3D optical data storage. |
SPEAKER INTRODUCTION:Georgiy Shakhgildyan received his Specialist degree in Chemical technology from Mendeleyev University of Chemical Technology of Russia (MUCTR). In December 2015 Georgiy received Candidate of Science degree in chemical science. Defense was held in MUCTR. The title of thesis is “Phosphate glasses, activated by metal nanoparticles and rare earth ions”. His scientific interests are development of new glass based functional materials and its femtosecond laser modifications, characterization of these materials in terms of structure and physical properties using optical and structural methods of investigation. |
