In an effort to create simpler next-generation lighting solutions, researchers from the University of Turku in Finland have developed a color-tunable white OLED. It is a top light-emitting device that ...

Abstract: Improving hole injection/transport and achieving charge balance through a multilayer hole-transporting layer (HTL) structure is a key technology for enhancing the performance of perovskite ...

Dermatologists explain the science behind wildly popular treatments like red light therapy, which is now available at home—for a steep price. Full-face LED masks like this one can cost up to several ...

A deep blue organic light-emitting diode (OLED) developed by researchers at Science Tokyo operates on just a single 1.5 V, overcoming the high-voltage and color-purity problems that have long limited ...

This illustration depicts the QAO family dopant integrated into the organic light-emitting diode structure. By designing a molecule with a lower HOMO level than that of the host material, the ...
