Tuned LED lighting that changes color and intensity over the course of a day and night helps older adults in nursing homes get a better night's sleep.

Our research identified three key lessons.

Halide perovskites are cheap, versatile and remarkably efficient as both solar cells and light emitters.

"Nobody had engineered a way to control the emission of light from an LED into a single direction."

Researchers are working on UV LED lights that could rid surfaces, and potentially air and water, of the coronavirus that causes COVID-19.

New tech could cut down on the light scattered inside current quantum dot light emitting diode (QLED) screens, making them way more energy efficient.

Putting edible tags made of proteins on pills could help fight back against counterfeit drugs, which claim thousands of lives each year.

LED lighting in greenhouses enhance plant growth but researchers say standards could make them even more effective.

A new kind of semiconductor made from barium zirconium sulfide instead of silicon could pave the way for better solar panels, LEDs, and sensors.
