Call for Papers: Thematic series on OLED Materials for Lighting

The Journal of Solid State Lighting welcomes submissions to the new thematic series on OLED Materials for Lighting.

Over the past three decades, organic light-emitting diodes (OLEDs) have attracted much attention due to their potential applications in displays and lighting. As promising candidates for lighting applications, OLEDs have several advantages compared with established light sources, such as incandescent bulbs, fluorescent tubes or inorganic LEDs: they are flat area emitters offering pleasant diffuse light perception, wide viewing angles, vivid colors, light and thin luminaires, and the possibility to be made transparent or to be processed on flexible substrates by low cost processing. At present, white OLEDs are capable of achieving a lifetime of more than 200 Khrs, the power efficiency of OLEDs has reached over 100 lm/W, and OLED luminaires are now available for domestic use. However, there is still a long way before we reach the goal of making OLED light sources with great lifetime and efficiency at low cost. In view of this, the potentially large market for OLEDs is driving both the academic and industrial community towards the development of new materials and advanced device manufacturing technologies.

We are inviting authors to contribute original research articles with a focus on OLED materials for lighting.

Potential topics include, but are not limited to:

  • Developments of novel red, yellow, green, blue emitter materials (fluorescence, phosphorescence, thermally activated delayed fluorescence) for white OLEDs
  • Development of high efficiency single-white polymers for white OLEDs
  • Development of transport and matrix materials suitable for white OLEDs
  • Emitter orientation
  • Interconnect technologies (charge generation layers, interstack-electrodes)
  • Substrates and electrodes for flexible devices
  • Light outcoupling approaches through novel material design
  • Materials for improved OLED stability
  • Advanced material modelling for OLEDs
  • Low cost OLED material production
  • Quantum dot/organic hybrid materials for white OLEDs

Call for Papers: Solid State and Organic Lighting (SOLED) in China 2015

As a member of the program committee, it is my pleasure to announce the Call for Papers for the Solid State and Organic Lighting (SOLED) Conference in Suzhou, China 2015. The deadline for abstract submission is 7 July 2015 12:00 EDT. The SOLED will take place from 02 – 05 November 2015. It will be a great conference, bringing together the key experts in the field. Keynote speakers include Stephen Forrest, University of Michigan, USA and Jung Han, Yale University, USA.

Nature Materials ‘focus on LED technology’: The future is more than just inorganics.

The May (2015) issue of Nature Materials contains a ‘focus on LED technology‘, surely motivated by the UNESCO International Year of Light 2015 and the Nobel Prize in Physics 2014 acknowledging the discovery of highly efficient blue gallium nitride (GaN) light-emitting diodes (LEDs). The latter actually set the basis for the current revolution in lighting technology we all witness.

But there is more than just LEDs made from inorganic semiconductors like GaN (an more complex GaN-based ternary alloys), which produces white light when paired with downconversion phosphor materials. LEDs made from organic semiconductors (OLEDs) or quantum dots (QD-LEDs) are alternative, high efficiency device concepts that offer to participate in the transition to an all solid-state light source future. I got a chance to comment on both technologies in the above mentioned Nature Materials focus (Complementary LED technologies).  With respect to all major LED technologies (LED, OLED, and QD-LED), if there is one thing that I wish we will see in future is the coexistence of all different concepts, where each application is further advanced by the most suitable architecture.

DOE discusses LED and OLED R&D challenges

The US Department of Energy is supporting R&D efforts to realize solid state lighting (SSL) using both LEDs and OLEDs through their DOE SSL R&D program: the Multi-Year Program Plan. Now DOE recently published to separate videos with experts’ views on the matter. I always find it very beneficial to have the both technologies – LEDs and OLEDs – very close together – be it in DOE workshops or now in this digital format – because it allows to interact directly between the different technology camps. In the end, both system have in common that their are high efficiency, environmentally friendly concepts that should find highest market acceptance/share at the earliest possible time.

2013 DOE Solid-State Lighting – Manufacturing R&D Workshop

Are you interested in the current wave of clean tech for general lighting – solid state lighting – and especially in the way it is done? The Department of Energy (DOE) is hosting its fifth Manufacturing R&D Workshop in Boston, MA. Time: June 5-6, 2013. A great opportunity to meet the US experts in the field. I like these meetings, because they are tightly focussed and cutting-edge.

A personal note: I find these meetings very interesting also, because they bring the real technological problems – big or small – to the table, without the general ‘all great’ we get from the companies PR.

New review article on white OLEDs for SSL

The lighting sector currently sees a major overhaul, mainly driven by the urge to install and use light sources with highest possible energy efficiency in all sectors of our life (industrial and residential). Solid state lighting is the key technology in this change of generations, where both inorganic and organic light-emitting diodes (OLEDs) aim to reduce our energy use. More importantly, they both offer to maintain or even improve the color quality of artificial light.

The research effort on developing OLEDs for general lighting has been started roughly 20 years ago by Professor Junji Kido (Japan) and since then, the field has seen tremendous progress and also a variety of approaches to realize white light. Tracking, to which extend white OLED research has broadened over the years and where the key technologies are, is a task of its own. Together with my colleagues at the TU Dresden, Germany (group of Prof. Karl Leo), I have been working on a review article focussing on white OLEDs for solid state lighting. It has recently been accepted and will be published in Reviews of Modern Physics later this year. To bridge the gap till final publication, we made it available as a preprint: White organic light-emitting diodes: status and perspective.
