Organic Light Emitting Devices: Charge Transport and Photo-physics

About this project

Project description

Research field of organic semiconductors has significantly progressed and now it is regarded as a promising field for the future. So far, this research area has led to the appearance of high-end commercial consumer products, e.g. the Samsung Galaxy mobile OLED displays/tablets and LG OLED TVs. One area of organic semiconductor that is in its infancy stage is semi-transparent display for augmented reality applications. Such display requires much higher brightness (and current density) typically exceeding >5,000 cd/m2. As the current injection levels increase in OLEDs, efficiency roll-off, and degradation of organic material becomes prominent. To design better lumophores needed for these applications, it is essential to understand the physics of radiative and non-radiative recombination of excitons. This project seeks to develop such an understanding through a dual track of photophysical investigations and novel synthetic methodologies.


The expected outcomes include creation of novel light emitting devices, establishment of new knowledge of structure-property relationship of materials, new fundamental understanding of device physics, and creation of new transparent light-emitting pixels for augmented reality (AR) – a combination of real and virtual world. This joint research project is highly multi-disciplinary, bringing leading chemists, physicists and engineers together. The project is also very fundamental and proof-of-concept in nature (both in materials and devices development) and the successful outcomes will have significant impacts to the academic communities and be of immediate interest to the related industrial sectors.
