Nanostructures Enable Step Toward OLED Lasers

Facebook X LinkedIn Email
Organic LEDs made with finely patterned nanostructures can produce bright, low-power light sources, a key step toward making organic lasers. Researchers have long dreamed of building organic lasers, but they have been hindered by carbon-based semiconductors’ tendency to operate inefficiently at the high currents required for lasing due to overheating.
