  O'Carroll Research Group
Nanophotonics and Organic Optoelectronics
 
     
The O'Carroll Group studies light generating and light harvesting processes in organic polymer semiconductor materials and plasmonic nanostructures. Our research has a number of uses such as: light-management in thin-film organic opto-electronic devices; optically-active electrodes; nanoscale optical devices; and environmentally-friendly electronics and photonics.

Research Topics:
  - Stability and efficiency of organic light-emitting diodes (OLEDs).

- Plasmonic metasurfaces for light management in thin-film optoelectronics.

- Exciton-plasmonic coupling.

- Nanolasers and SPASERs.

- Organic, excitonic and nanostructured solar cells.

- Photophysics of organic conjugated polymers.

- Large-area, low-cost nanofabrication.

- Visible-wavelength nanoantennas.

- Life-cycle assessment and costing of photonic materials and devices.
