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.

International TADF Symposium in Frankfurt is upcoming

On Thursday, September 7, 2017, the International TADF Symposium (organized by cynora GmbH) will take place in Frankfurt. It will be a packed one-day event with a tight focus on OLEDs based on thermally activated delayed fluorescence (TADF). The event will bring together leading industry and academia to share new results and discuss upcoming developments. You can find all the details about speakers and program on the events webpage. It is definitely a very good opportunity to get in touch with the people working on this exciting material development.

ECME 2017 in Dresden

This year, the 14th European Conference on Molecular Electronics (ECME) will be
held in Dresden on August 29 – September 2, 2017. Important date to remember and of course consider is the deadline for the Call for Papers, which is March 31, 2017. Please check it out to learn more about the different topics the conference will cover. The event already has  a broad and exciting collection of invited speakers and now it is looking for your contribution to turn it into a great and vivid week of molecular electronics science.

MRS Spring 2016 – Symposium EP1: the friday sessions are here

Its the last day of MRS Spring 2016 and still we are by far not done with our Symposium EP1: Organic Excitonic Systems and Devices. We have a full day of oral presentations split into two major sessions.

EP1.7: Advanced Organic Devices and Modeling

As the title indicates, some new concepts for devices based on organic materials will be central in this session. This is complemented by some efforts on modeling. Keywords for this session are:

  • Stretchable electronic structures
  • Modeling exciton and polaron dynamics for transient EL in OLEDs
  • Nanoscale electrical inhomogeneities in OLEDs
  • Visible light communications with organic systems
  • Method to predict interface barriers in OLED layers
  • Rare-earth up-conversion composites for PV

Our invited speaker in the morning is Graham A. Turnbull. Note: Franky So was not able to come to Phoenix, so that his presentation is cancelled. Klaus Meerholz had his talk already late last night.

EP1.8: Excitonic Charge Transfer States

Our final look in this last session is on charge transfer states and related phenomena. Most naturally, this is the time, where we will have presentations that are closer to photovoltaic properties than in the days before. Actually, this session closes the loop to the first sessions of the week, where we were guided a lot by internal charge transfer states in TADF materials.

Here are some details to the post-lunch session:

  • Enhancing exciton dissociation rates at heterojunctions using FRET
  • CT state transport at donor-acceptor blends
  • Magnetic field modulation of exciton recombination
  • Tailoring interfaces using additive engineering
  • Generation and modulation of chi^2 optical non-linearities
  • Printing highly efficient solution processed solar cells
  •  Multiple CT states in ordered and disordered systems

Max Shtein will be our invited speaker of the afternoon session.

See you around!

This afternoon, we are progressing with the general scheme of topics with the session EP1.5 Excitons in Organic and Hybrid Systems II of our Symposium EP1. Important: We have one additional speaker in the afternoon: Klaus Meerholz – his talk got shifted from Friday to this session. The following topics we will see:

  • NIR EL from surface plasmons
  • Area light-emitting transistors
