Researchers of international laboratories of Nano-Bioengineering (LNBE) and Hybrid Photonic Nanomaterials (ILPNM) presented results of studies at "Saint-Petersburg OPEN 2019" international conference

In late April, 6th International School and Conference "Saint-Petersburg OPEN 2019" on R&D in photonic nanostructures and their applications in laser physics, photovoltaics, biophysics, plasmonics, and many other areas was held in St. Petersburg, Russia.

The statement by Maxim Lednev, master's degree student of NRNU MEPhI and engineer of the International Laboratory of Hybrid Photonic Nanomaterials (ILPNM) (M. Lednev, D. Dovzhenko, Y. Rakovich, I. Nabiev. Numerical modelling of the spectral and spatial distribution of the electromagnetic modes in a tunable microcavity for investigation of the light–matter interaction) summarized the results of numerical simulation of the optical properties of a unique microcavity designed in NRNU MEPhI for research in strong light–matter coupling. At the conference closing, the author was awarded a diploma for the best report.

The statement by Daria Dyagileva, master's degree student and engineer of ILPNM (D. Dyagileva, V. Krivenkov, P. Samokhvalov, Yu. Rakovich, I. Nabiev. Two-photon absorption and photoluminescence of a thin-film hybrid material based on CdSe/ZnS/CdS/ZnS semiconductor quantum dots) presented research in two-photon processes in thin films based on semiconductor quantum dots and quantum nanoplates. In this study, the main parameters of these structures upon two-photon excitation were determined. In addition, the interaction of quantum dots and plasmonic nanoparticles in hybrid nanomaterials were studied. By observing a single, individual quantum dot, the authors discovered the enhancement of a quantum dot's biexciton luminescence caused by the influence of neighboring plasmonic nanoparticles. Insight into the factors determining the strengths of the effects of two-photon absorption and luminescence in plasmon–exciton hybrid materials will make it possible to determine the optimal conditions for designing next-generation photovoltaic and optoelectronic devices with an enhanced efficiency of solar energy conversion.

The reports by the researchers of LNBE and ILPNM presented at the "Saint-Petersburg OPEN 2019" will be published in journals cited in the Web of Science, Scopus, eLIBRARY, and other databases.
