Organic light emitting diodes (OLEDs) have revolutionized the display industry with flexible and thin displays of high colour contrast. We can already see applications of OLED displays in smart phones and TV screens including curved TVs.

It is also a very promising technology for the next generation of solid state lighting. A very recent and emerging area is the application of organic electronic devices including OLEDs for wearable biomedical sensors.

OLEDs are a desirable candidate for such applications because they can be completely flexible and stretchable and therefore have the potential to confirm to any shape of the body. To sum up, OLEDs are very versatile and have many applications.

The principal aim of this project is to study OLEDs for applications in solid state lighting, displays, wearables and/or biomedical sensing. The project will focus on designing OLEDs using different types of organic semiconductors and thin metal films, fabricating the designed OLEDs and testing them.

Research activities

This project will involve a lot of hands on experimental work using a variety of sophisticated equipment, including a system of glove boxes, which can fabricate organic electronic devices in an inert environment in the Central Analytical Research Facility.

Various aspects of OLEDs will be addressed such as improving the light out-coupling efficiency & therefore increasing the overall efficiency of OLED, flexibility of electrodes to achieve flexible OLEDs and optical tuning of OLEDs to get light emission of desired wavelength.
