SPIE Photonics Europe 2018: Join us at a new Conference EPE117

At the upcoming SPIE Photonics Europe 2018 (April 22-26, 2018) in Strasbourg, France, my colleague Koen Vandewal and I organize a new Conference called Organic Electronics and Photonics: Fundamentals and Devices (EPE117). The Call for Papers reads:

Organic materials are interesting for a myriad of photonic and optoelectronic applications due to their tunability of key electronic and optical properties, their versatility of processing, the softness of the solid films formed, and their potential to allow for non-toxic materials. Currently monochrome organic light-emitting diodes are a commercial product used in displays, while organic photovoltaics and sensors for low cost, bio, artificial skin, or wearable applications have seen rapid development in de latest years. On the basis of this very versatile material platform, it is expected that many more, innovative application concepts will be discovered and developed.

Hereby does fundamental research on organic electronics and photonics form the backbone for the discovery of new applications, especially, when materials’ properties are evaluated free of pre-determined applications. Moreover, basic experimental and theoretical research on charge, energy and spin transfer processes, organic-organic interfaces and their electronic structure, will provide structure-property relations and progress existing applications.

The focus of this conference will be on the following topics:

  • optoelectronic organic devices including light-emitting diodes, solar cells, photodetectors, sensors, transistors and switches
  • organic optical systems: waveguides, energy converters, cavities, light directors
  • organic bioelectronics with focus on optics
  • basic research in organic electronics and photonics: spectroscopy, charge generation, transport and recombination, spin,
  • charge and electron transfer interfaces, theoretical calculations and modelling, structure-property relations.

The deadline for abstract submission is October 23, 2017, so a couple of weeks to go.

We encourage you all to submit an abstract and join us for an exciting and inspiring week of fruitful scientific exchange.


ICEL ’10 – 2014 Cologne

Currently, the 10th International Conference on Electroluminescence and Organic Optoelectronics (ICEL ’10) is held in Cologne, Germany (August 31 – September 3, 2014) and I am happy that I decided to attend. The organizers (Klaus Meerholz, Selina Olthof, and Dirk Hertel) have set up a great conference bringing together a critical mass of experts in the field.

Some highlights from Monday and Tuesday: Stephen Forrest reports on improved OLED lifetime (10x) for blue phosphorescence achieved by exciton management; John Lupton summarizes his efforts on using organic molecules to probe singlet and triplet states and highlights some recent results on mapping both excitonic and nuclear spins in optoelectronic devices; Klaus Müllen presents his groups effort on bottom-up approaches to realize graphene nano structures with perfect order through organic synthesis; Mark Thompson shows very interesting results in applying symmetry breaking charge transfer molecules to increase the OPV open circuit voltage.

In general, there is a great representation of both recent efforts on thermally activated delayed fluorescence (TADF) and sophisticated optics for enhanced OLED light outcoupling. The results presented are remarkable. Another topic that got very good attention is emitter dipole orientation – we are seeing the transition from observation to attempt of understanding the effect. For tomorrow, we are expecting a refresh of the work of Chihaya Adachis group in his plenary talk early in the morning (Wednesday).

If you are not here, you should consider coming for the next meeting in two years from now. Following the tradition of alternating continents hosting the conference, the US is expected to host in 2016.

MRS Fall 2013: Kick-off your week with a tutorial

As a part of our Symposium N (Functional Aspects of Luminescent and Photoactive Organic and Soft Materials), in a joint effort with the organizers of Symposium Q (Organic Microlasers–From Fundamentals to Device Application), we offer a tutorial to start the exciting week of research: Tutorial N/Q: Organic Optoelectronics – Introduction to Materials and Device Physics. We a delighted that we are having two experts in the field, Prof. Mark E. Thompson and Prof. Wolfgang Bruetting, giving this introduction. The tutorial will start at Sunday, December 1, 1:30pm until 5pm that day. Location: Hynes Convention Center, Level 2, Room 203. We are all looking forward to this event and would like to invite everyone interested to come. Please spread the word.
