An upconversion organic light-emitting diode (OLED) based on a typical blue-fluorescence emitter achieves emission at an ultralow turn-on voltage of 1.47 V. The technology circumvents the traditional ...

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 ...

Colloidal quantum dots (QDs) exhibit exceptional properties of narrow-band emission, tunable luminescent wavelength, high luminous efficiency, and remarkable material stability across the visible and ...

Tokyo, Japan – Scientists from Tokyo Metropolitan University have developed a new electrode material for deep-ultraviolet (DUV) light-emitting diode applications. They used a cutting-edge deposition ...

To be more energy efficient, many people have replaced their incandescent lights with light-emitting diode (LED) bulbs. However, those currently on the market emit a lot of blue light, which has been ...

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 ...
