Profile and Testimonial from a NANO-PHOT M2 Student
Youna MAHE, UTT Engineering Degree and NANO-PHOT Master’ s Dual Degree
“ After completing a preparatory class in physics and chemistry after High School, I enrolled at the University of Technology of Troyes( UTT) in the Materials Engineering program:“ Materials; Technology and Economics,” which I complemented with a dual master’ s degree in Nanophotonics and Nano-Optics at the Nano-Phot Graduate School, taught in English. Combining theory and practice, my academic path has equipped me with a wide range of skills in simulation, fabrication, and cleanroom characterization of nanoscale devices, while also providing project management experience through my academic and extracurricular initiatives. For example, during a six-month engineering internship in R & D at Safran Reosc, I worked on the structuring of optical filters and optimized thin-film etching processes. During my master’ s program, my student project at the L2n laboratory( UMR CNRS 7076) is focusing on strong photon-plasmon coupling applied to biosensors. The graduate school environment, characterized by major international partnerships and a wide diversity of backgrounds, adds an international dimension to my academic journey. Photonics represents a strategic technological, geopolitical, and societal challenge, making it a field that aligns with my professional ambitions. After completing my final-year internship, I would like to pursue a CIFRE thesis within a company or a VIE program to contribute to innovation efforts in research or industry."
PLASMON-ASSISTED NANOCHEMISTRY
Nano-chemistry assisted by localized surface plasmons is a topical field. Understanding and controlling the associated physico-chemical effects could be exploited in the context of the energy crisis: using light as a source to generate and harvest chemical energy. An important question that is the subject of much debate and numerous studies is the respective contribution of optical near-field, hot electrons and local heat to the chemical reaction. This question necessitates the use of selective chemical systems. Within the NANO-PHOT graduate school, we have recently contributed to this debate by using a polymerizable system based on a diazonium salt, which excludes the contribution of the optical field due to its zero photon absorption in the visible and infrared regions, even in a multi-photon process. This selectivity has enabled us to highlight the contribution of hot electrons and local heat to diazonium polymerization triggered by the excitation of plasmonic modes in gold nanocubes, depending on the irradiation conditions( continuous illumination, ultrafast fs illumination, excitation wavelength, etc.).
