The research team led by Prof. Sergio Brovelli of the Department of Materials Science of the University of Milano-Bicocca, together with the research group led by Prof. Liang Li from Jiao Tong University and the Shanghai Institute of Ecological Safety and Pollution Control, developed innovative light emitting diodes (LEDs) with record efficiencies even at high operating temperatures, which are typically detrimental to traditional devices.
The results of the research have been published in Nature Photonics in the paper entitled “Suppression of Temperature Quenching in Perovskite Nanocrystals for Highly Efficient and Thermally Stable Light Emitting Diodes” (DOI: 10.1038/s41566-021-00766-2)
These results mark a turning point in artificial lighting technology. LEDs indeed generate heat during their operation: realizing emissive materials characterized by stable and efficient luminescence at high temperatures is therefore essential to obtain high performance LEDs for real world application.
