Energy-saving LED lighting is already sold in stores, but widespread adoption has been slow because of the costs associated with the material and the quality.

"We came up with our novel approach to solve some critical problems and get a high-performance LED," said associate professor Biwu Ma.

The researchers used an organic-inorganic hybrid form of the material perovskites to build the highly functioning LED.

After months of experiments using synthetic chemistry to fine tune the material properties and device engineering to control the device architectures, they ultimately created an LED that performed even better than expected.

The material glowed exceptionally bright. It is measured at about 10,000 candelas per square metre at a driving voltage of 12V. Candelas are the unit of measurement for luminescence. It was also quick and easy to produce.

The findings appeared in the journal Advanced Materials.
