A research team has developed a hierarchical-shell perovskite nanocrystal technology that simultaneously overcomes the ...

A domestic research team led by Professor Tae-Woo Lee (Department of Materials Science and Engineering, Seoul National ...

This mismatch creates several problems. In QD-LEDs, some electrons pass through the quantum dot layer without encountering a hole, wasting energy. Others recombine inefficiently, releasing heat ...

a, Device structure and b, schematic energy band diagram of a hybrid LED. c, EL spectra, d, current density-voltage, e, luminance-voltage and f, EQE- current density characteristics of the PeLED, OLED ...

We developed a hybrid copper–iodide compound called CuI(Hda). It emits deep-blue light at about 449 nanometres and has an almost-perfect photoluminescence quantum yield — a measure of emission ...

Leveraging the principles of quantum mechanics, quantum computers can perform calculations at lightning-fast speeds, enabling them to solve complex problems faster than conventional computers. In ...

Scientists have uncovered a previously unknown quantum state of matter that could reshape the future of computing, sensing, ...

Light-emitting diodes (LEDs) are prevalent in everything from digital clocks to solar panels, traffic lights, electronic banners and signs, Christmas decorations, as well as smartphone and tablet ...

Samsung Display showcased a next-generation display technology called QD-LED (quantum dot LED) at the Society for Information Display (SID) Display Week 2024. Currently, OLED is the only commercially ...

Quantum information can be carried in particles of light called photons. Single photon emitters that emit precisely one photon at a time are important components for many quantum technologies, ...
