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 ...

Halide perovskites have garnered attention because they're highly efficient at capturing energy in solar cells and efficient emitters in diodes. But researchers failed at making perovskite LEDs that ...

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 ...

Imagine a display that harvests ambient light when it is not actively in use, offsetting some of its own energy consumption. Materials physics shows that this is possible; the same semiconductor ...

LED lighting technology is increasingly adopted for its energy efficiency, durability, and longevity, making it an ideal solution for modernizing urban areas and developing smart city infrastructures.

Researchers created a new optoelectronic device from the combined use of Holographic Metasurfaces (HMs) and OLEDs.

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 ...
