Organic Opto-Electronics

The international research group 'Organic Opto-Electronics' (OOE) explores hydrocarbon based electronics for light sensing, emission or conversion into electrical energy. Research focuses on fundamental photo-physical processes at the molecular and meso-scale and how they determine device performance and their physical limits. In addition, the group aims at translating these insights into novel device concepts for future electronic applications in energy and healthcare.

Device Zheng BS

Polymer-Based Electronics

Devices based on semiconducting polymers benefit from a large variety of chemical structures and can be deposited using low-cost, solution-based deposition techniques.

Device Nat Comms

Small-Molecule Based Electronics

Devices based on vacuum-processed small molecules benefit from a solid reproducibility as well as an effortless lateral structuring and vertical stacking.

Dielectric Mirrors BB V2


Dielectric mirrors or distributed Bragg reflectors are high-quality mirrors with superior reflectivities up to 99.9%, rendering them ideal to combine with emitting or absorbing organic materials.

Laser Lab SM V2

Ultra-Sensitive Steady-State and Time-Resolved Spectroscopy

We study optical absorption and emission processes in thin film using a series of ultra-sensitive techniques.

Optical Field XJ V3

Molecular and Device Scale Simulations

We apply computational techniques to model processes on the molecular scale, such as the absorption and luminescence of molecules.

How to collaborate with OOE?

  • Joint research projects: research and development in close cooperation, financed by a third party (e.g. FWO, VLAIO, Horizon Europe, EFRO)
  • Technology/knowledge transfer: you can strengthen your market position through licensing and access to our existing technologies and expertise
  • Partnership: you can cooperate with DSOS and use our technology (possibly) in combination with your own technology to set up a new company
  • Scientific services: OOE has expertise in applied and contract research in collaboration with industry
