Researchers have designed smart, colour-controllable white light devices from quantum dots – tiny semiconductors just a few billionths of a metre in size – which are more efficient and have better colour saturation than standard LEDs, and can dynamically reproduce daylight conditions in a single light.
An international group of researchers has developed a new technique that could be used to make more efficient low-cost light-emitting materials that are flexible and can be printed using ink-jet techniques.
Today, the Nobel Prize for Physics 2014 has been awarded to Isamu Akasaki, Hiroshi Amano and Shuji Nakamura for their invention of a new energy-efficient and environment-friendly light source – the blue light-emitting diode (LED). University of Cambridge researchers are building on their work to produce more cost-effective gallium nitride LEDs that can have widespread use in homes and offices.
A breakthrough technique for manufacturing LEDs on silicon is to be exploited in the UK, putting mass-produced, energy-efficient lighting within reach.
A remarkable light-emitting material, gallium nitride, could slash electricity consumption, purify water and kill superbugs.
Cambridge has received £1.4 million funding to progress innovative energy solutions.
