That includes the light-emitting diodes, the circuit boards and the durable metal housing that protects the lights in news vans and on film sets.

This approach has been successful for decades in many applications, such as transistors, light-emitting diodes, lasers and quantum devices.

The team first experimentally measured the exciton binding energies for 42 organic semiconductors including 32 solar cell materials, seven organic light-emitting diode materials, and three crystalline compounds of pentacene.

These types of compounds could also be developed for use as light-emitting diodes for television and computer screens, Gilliard says.

Excitons are a key part of many technologies, including solar panels, photodetectors and sensors, as well as light-emitting diodes found in televisions and digital display screens.
