Overview
Personal Profile
Garry Rumbles joined NLR in 2000 and is widely recognized for his research in photochemistry and photophysics of conjugated molecular systems, energy conversion in organic light emitting diodes and organic photovoltaic devices, and nanoscale morphology.
Rumbles' research interests are in solar energy with a focus on the basic science of solar photoconversion processes and photoinduced electron transfer processes in polymer-based nanostructured interfaces. His primary research expertise lies in photochemistry and photophysics, with a specialty in kinetics.
Research Interests
Excited-state kinetics in synthetic polymers; cis-trans isomerization of natural chromophores in biomolecules; spectroscopy of transient, gas-phase molecules; photophysics at solid-solution interfaces; third-order nonlinear optical properties of conjugated molecules; frequency upconversion and optical refrigeration in dye solutions; and the fundamental photophysics of conjugated (electroluminescent) polymers, colloidal quantum dots, and single-walled carbon nanotubes
Laser-based experiments (time-resolved fluorescence spectroscopy; time-resolved resonance Raman spectroscopy; laser-induced fluorescence spectroscopy; time-resolved evanescent wave-induced fluorescence spectroscopy; picosecond coherent anti-Stokes Raman spectroscopy; transient absorption spectroscopy; and time-resolved microwave conductivity)
Organic photovoltaic research, exploring some of the more applied solar energy problems; using time-resolved microwave conductivity to study the dissociation and recombination kinetics of nanoscale excitons at interfaces formed between molecular-based species
