Project description
Boosting efficiency and stability of phosphorescent organic light-emitting diode technology
Phosphorescent organic light-emitting diodes (PHOLEDs) are widely used in displays and lighting. However, their limited operational lifetime and luminance remain significant challenges. Improving these factors is crucial for advancing OLED technology. With the support of the Marie Skłodowska-Curie Actions programme, the PLAS-PHOLEDs project aims to use plasmon-exciton polaritons – an innovative technology that enhances light emission efficiency. The target is to increase the lifetime and luminance of PHOLEDs tenfold. By optimising OLED microcavities, PLAS-PHOLEDs will reduce destructive interactions. A key breakthrough will be the development of purely organic room temperature phosphorescence (RTP) materials that offer an eco-friendly and cost-effective alternative. PLAS-PHOLED will set new benchmarks for near-infrared and RTP OLEDs, advancing their performance.
Objective
The ultimate objective of PLAS-PHOLED is to increase tenfold the operational lifetime and luminance of phosphorescent organic light-emitting diodes (PHOLEDs). I will achieve this by increasing the radiative rate of triplet states through the design and engineering of PHOLEDs that support plasmon–exciton polaritons (PEPs). PEPs were recently introduced by Prof. Forrest's group as a promising technology for increasing Purcell enhancement in the OLED stack . PEPs effectiveness in OLEDs is sensitive to the optical properties of the underlying microcavity effects which I plan to exploit to reduce the probability of forming destructive high-energy states via triplet–polaron and triplet-exciton collisions. PLAS-PHOLED will study OLEDs that emit from visible (blue, green and red) to near-infrared (NIR) regimes. While PLAS-PHOLED kicks off by studying organometallic complexes that will enable me to deeply understand the device parameters that best support PEP, it later extends to purely organic room temperature phosphorescence (RTP) materials. The latter is the key novelty of PLAS-PHOLED as it will enable the RTP compounds to reach microsecond radiative rates, matching those to organometallic counterparts, thus introducing the 5th generation of environmentally friendly and inexpensive OLEDs. For the first time, the results of this proposal will define the state-of-the-art in understanding NIR and RTP OLEDs coupled with microcavity to enhance their emission rate, outcoupling, and operational stability.
