Ultrafast Spectroscopy Symposium
Join us in on 24th January 2025 for a FREE one-day workshop on Ultrafast spectroscopic techniques. In conjunction with the Warwick Centre for Ultrafast Spectroscopy (WCUS), this event aims to allow students to get the most out of the techniques and learn best practices from technical and academic experts, as well as an opportunity to share how these techniques have enabled their research.
The event is being held at Scarman, University of Warwick, open to all and is FREE to attend.
We have talk slots available for PhD students - please contact Jack and Chris with an abstract and title. (jack.woolley@warwick.ac.uk christopher.waldron@warwick.ac.uk).

Dr Greg Greetham, Ultra Central laser Facility: Ultrafast Spectroscopy at the Central Laser Facility
ULTRA is one of the Central Laser Facility’s laboratories at the Rutherford Appleton Laboratories, focussing on time-resolved and non-linear spectroscopies. This is an open access facility for academia and industry, with applications in a wide range sciences from biomolecular dynamics to heterogeneous catalysis. An overview of the facility will be given, highlighting some of the science and technical developments at the facility. Current technical developments are focussed on HiLUX, a UKRI infrastructure funded project to install the next generation of ultrafast spectroscopy laboratories.
Dr Joseph Beames, University of Birmingham: Spectroscopy of novel organic and inorganic emitters: Towards rational spectroscopic design
Emissive chemical species are now essentially ubiquitous in our daily lives, found in everything from our lights, watches, phones to our mirrors and fridges (pretty much anything with ‘smart’ in the name). These applications are afforded by the chemical synthesis of carefully tuned organic and inorganic emitters that have precise spectroscopic emission profiles, emission lifetimes and emission quantum yields. This talk presents a combined experimental and computational chemistry insight into the use of small chemical substitutions of organic frameworks to modify photophysical properties towards those desirable for commercial applications, for example precisely tuning emission maxima in iridium complexes and enhancing triplet harvesting in organic emitters. More specifically my group use a range of laser-based techniques to probe the ground and excited state solution phase spectroscopies of these compounds alongside investigations of their excited state dynamics, complemented by ab initio computational approaches to model spectra, examine electronic transitions and predict non-adiabatic dynamics. In collaboration with several synthetic chemists, these data are used to assist in chemically modifying these emitters to rationally tune their photophysical properties. The spectroscopic datasets we generation are examined and discussed using many of the small molecule approaches that are employed within the Lester group, for example considerations of orbital symmetry and degeneracy, hindered internal rotations and computational spectral prediction.
Phosphorescence spectra of substituted Ir(III) quinoxaline complexes, some of which demonstrate impressive light upconversion quantum yields of >39% in the presence of diphenylanthracene (triplet-triplet annihilation upconversion).
