Reminder (TODAY): Trieste Quantum seminar - June 17th 2024, 4:00 pm CEST @UniTs DF - Martina Dell'Angela

[Infopoint]

The third seminar of "*Trieste Quantum*" will be held by *Dr. Martina 
Dell'Angela* (Consiglio Nazionale delle Ricerche CNR-IOM, Elettra 
Sincrotrone, Trieste, Italy):

Monday, June 17, at 4:00 p.m. – Aula A at Building F (Department of 
Physics, University of Trieste), via Valerio 2
*Title: Charge and Exciton Dynamics in Hybrid Materials Probed by Time 
Resolved Soft X-Ray Spectroscopies at ELETTRA Synchrotron *
*
*
*Abstract:* In the fields of optoelectronics and photochemistry there is 
growing interest in studying the response to optical excitation of 
organic molecules, films and interfaces, as these systems are of 
fundamental relevance for the development of the next generation of 
environmentally sustainable optoelectronic devices and catalysts. In 
order to probe the charge and exciton dynamics in such materials down to 
the sub-nanosecond timescale we developed a setup at the ALOISA beamline 
of the Elettra synchrotron that exploits the chemical selectivity of 
X-ray absorption spectroscopy (XAS) and X-ray photoemission (XPS) in an 
optical pump/X-ray probe experiment. In this talk, I will present our 
recent results on tracking triplet dynamics in pentacene and perylene 
thin films. The role of the film morphology will be discussed by 
comparing the response of perylene molecules with different 
terminations. Finally, I will show how the developed setup can be used 
to follow a structural transition in few examples of 2D-materials.

See you there!
