# Excilight: Exciplex-based OLEDs

### What is Excilight

Excilight is a Marie Curie Initial Training Network (ITN) which is funded as part of the European Union Horizon 2020 program. The objectives are to train the next generation of bright young scientists by tackling big resrearch projects.

The Excilight ITN is focussed on finding new ways to produce low-cost energy-efficient lighting based upon exciplex based OLEDs.

### Introduction

Lighting is a global and growing market. New forms of efficient solid state lighting (SSL) technology are rapidly gaining a major foot hold in the market. New OLED technologies (Organic Light Emitting Diode) are aimed at revolutionising both lighting and displays because of the flexible structure and tailor their properties, including the colour of emitted light, by modifying their structure. The forecast shows that the OLED lighting market will grow from $200 million in 2015 to$1.7 billion by 2020. In order to fully benefit from this huge market potential, Europe`s academia and industry are keen to develop new technologies and recruit highly qualified staff.

The high demand for flexible SSL lighting will increase the need for very expensive and rare iridium. The EXCILIGHT project aims to explore exciplex emitters and thermally activated delayed fluorescence (TADF) in OLEDs i) to replace currently used Ir complexes, and ii) to show how to easily tune emitter, resulting in reduced production cost.

Our EXCILIGHT network will therefore train a new generation of materials scientists for the development and application of exciplex and TADF emitters, who can apply their expertise directly in future positions. The training programme is characterised by a unique innovative and multidisciplinary approach, based on i) a combination of synthesis, characterisation and the formation of real devices for the lighting industry, ii) an appropriate balance between research and transferable skills training, and iii) a strong contribution of the private sector, including leading industry and SMEs, through mentoring, courses and secondments.

The 15 PhD students employed in the project will be exposed to individuals and organisations from different sectors, including top scientists from academia and industry.
