Excited-state dynamics
Thermally activated delayed fluorescence (TADF), room-temperature phosphorescence (RTP) and charge-transfer states in organic materials. The focus is on the mechanisms that govern emission and non-radiative decay.
Research
Photophysical and electrochemical processes in organic semiconductors.
My research examines the relationship between molecular structure, excited-state dynamics and device performance. Experimental spectroscopy and electrochemistry connect the properties of individual molecules with their behaviour in thin films and electronic devices.
Electronic structure and redox processes
Electrochemical and spectroelectrochemical characterisation of conjugated molecules and polymers, including the relationship between redox behaviour and the properties of optoelectronic active layers.
Materials for OLEDs
Development and characterisation of organic emitters, exciplex systems and hyperfluorescent materials. Connecting photophysical mechanisms with electroluminescence and device efficiency.
Organic energy materials
Research interests extend to organic thermoelectrics, redox-active storage interfaces and coupled light–heat–charge processes. These directions build on existing expertise in spectroscopy, electrochemistry and organic electronic materials.
Experimental methods
Electrochemistry and spectroelectrochemistry; steady-state and time-resolved spectroscopy; thin-film preparation; OLED fabrication and characterisation.
EXCITED-STATE PHOTOPHYSICS
Thermally activated delayed fluorescence
Thermal energy enables reverse intersystem crossing (RISC) from T₁ to S₁. Fluorescence then occurs from S₁ to S₀.
