Intrinsically stretchable quantum dot-based light-emitting diodes achieved record-breaking performance.
There has been a clear need for novel materials and device designs that can endure significant stretching while maintaining their functionality, which is essential for applications including wearable and adaptable interfacing technologies.The majority of the flexible displays on the market employ organic light-emitting diode technology, which employs organic materials as light-emitting components. However, OLED often has drawbacks such as limited brightness and color purity issues.
A significant hurdle encountered during this approach was the elastomers’ insulating properties, which impede the efficient injection of electrons and holes into the QDs, thereby diminishing the device’s electroluminescent efficiency.Hence the IBS researchers had to come up with innovations to overcome these limitations. Their work showcased the incorporation of a third material in the composite to enhance carrier delivery to the QDs.
