New research from the University of St Andrews paves the way for holographic technology, with the potential to transform smartdevices, communication, gaming and entertainment.

In a study published in Light: Science & Applications, researchers from the School of Physics and Astronomy created a new optoelectronic device from the combined use of holographic metasurfaces (HMs) and organic light-emitting diodes (OLEDs).

Until now, holograms have been created using lasers. However, researchers have found that using OLEDs and HMs gives a simpler and more compact approach that is potentially cheaper and easier to apply, overcoming the main barriers to hologram technology being used more widely.

Organic light-emitting diodes are thin film devices widely used to make the colored pixels...

Finding paves the way for new generation of opto-electronic applications. Quantum dots are clusters of some 1,000 atoms which act as one large ‘super-atom’. It is possible to accurately design the electronic properties of these dots just by changing their size...

Researchers introduce a novel device concept towards high-efficient and low-voltage vertical organic lighting-emitting transistors. With the new device architecture and fabrication technology, the team paves the way for a broad application of efficient OLED active matrix displays.

In the group of Prof. Karl Leo, physicists, material scientists and engineers are working jointly on the development of novel organic materials and devices for high performance, flexible and possibly even biocompatible electronics and optoelectronics of the future. Increasing the performance of organic devices is one of the key challenges in their research. It was only last year, when the team headed by Dr...
