Spray-on process creates bright, efficient LEDs
Researchers have developed a process to make light-emitting diodes by spraying a substrate with quantum dots (ACS Photonics 2017, DOI: 10.1021/acsphotonics.7b00216). The quantum-dot LEDs (QLEDs) are 100 times as bright and efficient as similar devices, the researchers say. The process could someday be used to mass-produce inexpensive, vibrant, and flexible displays.
Quantum dots are semiconductor nanocrystals that emit a single wavelength when stimulated . . .
