Artificial control of exciplexes opens possibilities for new electronics

Posted by in categories: computing, electronics, materials, solar power, sustainability

Demonstrating a strategy that could form the basis for a new class of electronic devices with uniquely tunable properties, researchers at Kyushu University were able to widely vary the emission color and efficiency of organic light-emitting diodes based on exciplexes simply by changing the distance between key molecules in the devices by a few nanometers.

This new way to control electrical properties by slightly changing the device thickness instead of the materials could lead to new kinds of organic electronic devices with switching behavior or that reacts to external factors.

Organic such as OLEDs and organic solar cells use thin films of for the electrically active materials, making flexible and low-cost devices possible.
