报告人简介：

Marcin Runowski is an Associated professor in Department of Rare Earths, Faculty of Chemistry, Adam Mickiewicz University (Poznan, Poland). He obtained his Bachelor degree, chemistry, UAM Poznań, Poland: 2008-2011 and Master studies, chemistry, UAM Poznań, Poland: 2011-2012. Hen, he obtained his PhD studies, chemistry, UAM Poznań, Poland: 2012-2016. Professor Marcin Runowski has significant achievement and made substantial contribution in the field of high-pressure and luminescence spectroscopy research, by developing several new optical sensors of high pressure and temperature working under extreme conditions. His research deal mainly with luminescence spectroscopy under high-pressure conditions, optical detection of phase transitions, development on new ultra-sensitive optical (luminescent) pressure sensors, as well as plasmonic sensors of phase transitions and refractive index operating in a diamond anvil cell (DAC) under extreme conditions. Marcin Runowski published over 140 papers in the high-IF journals, cited over 4500 cites, in the very prestigious journals, such as: Advanced Materials (IF = 29.4) Advanced Functional Materials (IF = 19.924), Advanced Science (IF = 15.1), Materials Horisons (IF = 12.2) Chemical Engineering Journal (IF = 16.744), Laser and Photonic Review (IF = 10.947), Advanced Optical Materials (IF = 10.05), ACS Applied Materials and Interfaces (IF = 10.383), etc.

报告摘要：

Optical pressure sensors, i.e., luminescent manometers, offer new possibilities for remote and non-invasive investigation and monitoring of changes in physicochemical and spectroscopic properties of materials under extreme conditions. This can be done by monitoring and analyzing selected spectroscopic parameters, such as band intensity ratio, emission line shift, or luminescence decay times. However, the limitation for optical readouts is usually the quenching of the luminescence signal in a given material, i.e., in the active part of the sensor under high pressure conditions. Here we show some new, promising strategies for the development of advanced and ultrasensitive pressure sensors, based on organic and inorganic materials containing lanthanide and d-block metal ions. The factors affecting the enhancement of luminescence signal intensity and sensor sensitivity will be discussed. These goals can be achieved through inter-ionic energy transfer, pressure-induced intersystem configurational crossover, and by using materials exhibiting both photo- and mechano-luminescence.
