Several pieces of evidence have suggested that blue light can inactivate various pathogenic bacteria. Previously in vitro and in vivo studies using blue light in the spectral range of 400–470 nm ...

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 ...

Exploring the evolution of LED lighting in cinematography, from red light solutions to the challenges of achieving deep blue and ultraviolet effects for more natural skin tones. It’s easy to assume ...

The absolute internal quantum efficiency (IQE) of indium gallium nitride (InGaN) based blue light-emitting diodes (LEDs) at low temperatures is often assumed to be 100%. However, a new study has found ...

With the invention of the first LED featuring a red color, it seemed only a matter of time before LEDs would appear with other colors. Indeed, soon green and other colors joined the LED revolution, ...

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 ...

Three scientists who succeeded in inventing efficient blue light-emitting diodes (LEDs) where many companies had failed have won the Nobel Prize in Physics. The Royal Swedish Academy of Sciences on ...
