A Rutgers-led team of scientists has developed an eco-friendly, very stable, ultra-bright material and used it to generate deep-blue light (emission at ~450 nm) in a light-emitting diode (LED), an energy-efficient device at the heart of all major lighting systems.
A Rutgers-led team of scientists has developed an eco-friendly, very stable, ultra-bright material and used it to generate deep-blue light (emission at ~450 nm) in a light-emitting diode (LED), an energy-efficient device at the heart of all major lighting systems.
The new copper-iodide hybrid emitter materials are expected to contribute to the advancement of blue LED technologies because of their excellent qualities, according to the scientists who pioneered the discovery. The process that produces the material is described in the science journal Nature.
“Deep-blue LEDs are at the heart of today’s energy-efficient lighting technologies,” said Jing Li, a Distinguished Professor and Board of Governors Professor of Chemistry and Chemical Biology in the Department of Chemistry and Chemical Biology in the School of Arts and Sciences who leads the study. “However, existing options often present issues with stability, scalability, cost, efficiency or environmental concerns due to the use of toxic components. This new copper-iodide hybrid offers a compelling solution, leveraging its nontoxicity, robustness and high performance.”
