Thermally activated delayed fluorescence – as a solution to the low yield problem of the fluorescent OLEDs
Journal Title: CHEMIK nauka-technika-rynek - Year 2016, Vol 70, Issue 6
Abstract
The development of display technology led to invention of OLED screens whose use is becoming more common nowadays. Today one of the goals is to improve OLED external quantum efficiency (EQE). Organic light-emitting diodes have always suffered from limited quantum efficiency due to harvesting of only 25% of excited states. TADF, which is thermally activated delayed fluorescence, allows to harvest up to 100% of excited states formed in the OLED, thus to decrease a contribution of the non-radiative relaxation. This phenomenon occurs for molecules possessing a small integral overlap of HOMO and LUMO, which results in a small singlet- triplet energy gap.
