Lighting is a global and growing market. New forms of efficient solid state lighting 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 EXCILIGHT ITN is focussed on finding new ways to produce low-cost energy-efficient lighting based upon exciplex based OLEDs.

The scientific challenges which drive the EXCILIGHT project are:

  • To fully understand the TADF mechanism so that new, highly efficient emitters can be designed, from the red to the blue
  • To synthesise highly efficient TADF emitters and to replace Ir complexes
  • To investigate multilayer TADF devices and new device architectures for full TADF white light emission
