Researchers Develop LED Technology Utilizing Gold-Copper Alloy Nanoclusters

Researchers at the University of Calicut have achieved a breakthrough in LED technology by developing a novel light-emitting device using gold-copper alloy nanoclusters. Led by Dr. Shibu Sidharth and his PhD student Dr. Rival Jose, their nanocluster-based LED (NC-LED) boasts a remarkable external quantum efficiency (EQE) of 12.6%, one of the highest for its type. This significant advancement has been published in Advanced Materials, a prestigious journal, marking the university’s first appearance in such a high-impact publication. The eco-friendly and sustainable manufacturing process eliminates the use of toxic materials, showcasing the potential for scalable applications. Dr. Sidharth noted the importance of this research in reinforcing the capability of Indian state universities to produce impactful scientific innovations.
