Quantum dot light‐emitting diodes (QD‐LEDs) represent a versatile class of optoelectronic devices that harness the unique properties of semiconductor nanocrystals to produce highly saturated and ...

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 ...

Quantum dot light-emitting diodes (QLEDs) have received considerable attention during these years. Considering that about 15 percent of the global electricity was used on lighting, these advantages ...

Quantum dots are nanoscale crystals capable of emitting light of different colors. Display devices based on quantum dots promise greater power efficiency, brightness and color purity than previous ...

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 ...

Researchers have designed smart, color-controllable white light devices from quantum dots -- tiny semiconductors just a few billionths of a meter in size -- which are more efficient and have better ...

Miniaturization ranks as the driving force behind the semiconductor industry. The tremendous gains in computer performance since the 1950s are largely due to the fact that ever smaller structures can ...

QLED TV manufacturers have dug themselves into a hole. After years of companies promising that their quantum dot light-emitting diode TVs use quantum dots (QDs) to boost color, some industry watchers ...

A new publication from Opto-Electronic Sciences; DOI 10.29026/oes.2025.240028 , discusses eco-friendly quantum-dot light-emitting diode display technologies. Colloidal quantum dots (QDs) exhibit ...
