报告摘要

Excitonic materials, including conjugated polymers, exhibit complex photophysical behavior that influences their performance. Since for many applications these materials are in films, the morphology and photophysical behavior in this form must be understood and sometimes controlled. any of these processes occur on ultrafast timescales and in small spatial domains requiring advanced time-resolved optical micro-spectroscopic techniques to fully interrogate their photophysics. In this talk I will outline our developments of a range of optical microscopy and ultrafast laser spectroscopy methods including time-resolved and polarized fluorescence microscopy, femtosecond transient infrared spectroscopy and transient absorption microscopy applied to investigate various excitonic materials such as polymeric systems, and discuss future directions.

个人简介

Trevor Smith obtained his BSc (Hons) and PhD degrees from the University of Melbourne before being awarded an Australian National Teaching Company Scheme Scholarship. He then completed a post-doctoral position at Imperial College, London before returning to the university of Melbourne as an Erns & Grace Matthaei Research Fellow, He was subsequently awarded an ARCOEI Fellowship investigating applications of time-resolved, multiphoton and confocal microscopy. He was appointed as a lecturer in 2004 and is now Professor & Reader in Chemistry, He has been a Chief Investigator in the ARC Centre of Excellence in Exciton Science since 2017. His research interests are in the broad area of photochemistry/photophysics specializing in ultrafast laser spectroscopy and optical microscopy applied to systems including organic and other photovoltaic materials.
