Development of White Electroluminescence Devices Based on Multi-exciplex Emitters (OWEX)


Project no.: P-MIP-17-196

Project description:

This project is focused on synthesis and characterizations of the versatile exciplex-forming donor-acceptor (D-A) compounds and the development of white organic light-emiting diodes (OLEDs) based on such compounds with a view to make the solid-state lighting maximally effective. We propose the development of new type exciplex forming foundation, enabled the formation two different types of D-A/D and D-A/A exciplexes in the same time. The utilization of the latter would allow to obtain white emission in simplified OLED structure.

Project funding:

Projects funded by the Research Council of Lithuania (RCL), Projects carried out by researchers’ teams

Project results:

A prototype of white low-cost organic light emitting diodes will be developed with simplified structure due to the employment of the newly synthesized versatile exciplex-forming D-A compounds as emitters exhibiting thermally activated delayed fluorescence (TADF); high photoluminescence quantum yields (PLQY); high and balanced charge mobilities (~10-3 cm2/Vs); high triplet-energy values (>2.8 eV) and appropriate energy levels.

Period of project implementation: 2017-09-01 - 2020-09-30

Project coordinator: Kaunas University of Technology
