Atom swapping could lead to ultra-bright, flexible next generation LEDs

An international group of researchers has developed a new technique that could be used to make more efficient low-cost light-emitting materials which are flexible and can be printed using ink-jet techniques. The researchers, led by the University of Cambridge and the Technical University of Munich, found that by swapping one out of every one thousand atoms of one material for another, they were able to triple the luminescence of a new material class of light emitters known as halide perovskites.

Headed by the University of Cambridge and the Technical University of Munich, the researchers discovered that by swapping one out of every one thousand atoms of one material for another, they could increase the luminescence of a new material class of light emitters, called halide perovskites, by three-fold.

New imaging system allows us to see UV and visible light simultaneously

When it comes to light, there’s a lot more than meets the human eye.
While people can see visible light in the wavelength range between 400 and 700 nanometers – that rainbow between violet and red – there’s a lot of information our eyes can’t detect in the slightly longer wavelengths of near infrared and shorter wavelengths of the ultraviolet range. Various systems to make UV light visible to the human eye have been on the market for years and used to inspect electrical insulation and in criminal forensics, astronomy and photography. But those typically require a power source and electronic components.
