Researchers have designed and tested ‘human-centric’ LEDs that emit different wavelengths of blue light depending on whether it’s daytime or nighttime, reducing the disruptive effect artificial light ...

It’s hard to believe that the first blue LED didn’t arrive until 1993. They look simple, but looks are deceiving (Fig. 1). 1. Image showing a blue InGaN-based LED with gold wire contacts (0.4 × 0.4 mm ...

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 ...

Kopin Corp. has developed a nanotechnology-based process to produce blue LEDs that the company claims are as bright as commercial blue LEDs yet can operate at lower voltages. The Taunton, Mass., ...

I FUCKING HATE BLUE LEDS.<BR><BR>Actually. I don't hate the actual LEDs themselves. I hate it when they have been incorporated into something purely for the BLING ...

(Nanowerk News) From street and household lighting, to television and mobile displays, light emitting diodes (LEDs) play an essential role in modern life. Now, researchers from the Okinawa Institute ...

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 ...

LEDs work by converting electrical energy into photons in a layer made of a semiconductor. Research into new semiconductor materials is key not only to further improving the energy efficiency of these ...

For the first time, researchers have created blue LEDs using layers of metal halide perovskite linked with asymmetrical bridges, solving a critical instability problem. Metal halide perovskites are a ...
