Light-emitting diodes (LEDs) are so ubiquitous that it's easy to forget just how much society relies on these underappreciated technological wonders. Yet, the history of the LED goes back further ...

We've had success in converting longer wavelength blue LED light into shorter wavelength UVA. So, our next step was to find compounds that could convert blue LED light to UVB," explains Yanai.

A Rutgers-led team of scientists has developed an eco-friendly, very stable, ultra-bright material and used it to generate deep-blue light (emission at ~450 nm) in a light-emitting diode (LED), an ...
