Mixed halide perovskites for spectrally stable and high-efficiency blue light-emitting diodes. Researchers at Linköping University, Sweden, have developed efficient blue light-emitting diodes based on halide perovskites. “We are very excited about this breakthrough,” says Feng Gao, professor at Linköping University. The new LEDs may open the way to cheap and energy-efficient illumination.

Illumination is responsible for approximately 20% of global electricity consumption, a figure that could be reduced to 5% if all light sources consisted of light-emitting diodes (LEDs)...
