O-LEDs: Efficient emitters in the NIR-II window

News & Views in Nature Photonics by Alessandro Minotto

Alessandro Minotto, a researcher in Experimental Physics of Matter at the Department of Materials Science, University of Milano-Bicocca, has been invited by the editors of the prestigious scientific journal Nature Photonics (Impact Factor 39. 728, Journal Citation Report (Clarivate Analytics, 2021)) to write a News & Views editorial article on efficient organic LEDs (O-LEDs) emitting in the spectral range extending from 1000 to 1700 nm, the so-called NIR(Near Infrared)-II second window. The title of the paper is "Efficient emitters in the NIR-II window" (DOI: 10.1038/s41566-022-01109-5). Alessandro's research activity focuses on the growth and characterization of crystalline organic films, with the aim of integrating them into optoelectronic devices. Alessandro has also co-authored several articles and reviews on NIR OLEDs. For these reasons, the journal invited him to write a supporting editorial for an article published in the same issue (DOI: 10.1038/s41566-022-01079-8), reporting record photoluminescence and electroluminescence efficiencies in the NIR-II from crystalline films of organo-metal complexes.

About Alessandro Minotto

A researcher in Experimental Physics of Matter in the Department of Materials Science since December 2021, he received his MSc degree in Materials Science in 2011 from the University of Padua, where he also obtained his Ph.D. in Materials Science and Engineering in 2015 (Thesis title: Characterization of CdSe-CdxZn1-xS core-shell quantum dots as active materials for compact microcavity lasers). From 2015 to 2019, he worked as a Post doc at the London Centre for Nanotechnology and University College London (UK), where he became an expert in the field of organic semiconductors, particularly in the fabrication and characterization of NIR OLEDs. For about two years (2020-2021), he combined his expertise in the field of quantum dots and optoelectronic devices, working as a senior researcher on quantum dot LEDs at Sharp Laboratories of Europe (Oxford, UK). At the end of 2021, Alessandro took up his current position as RTDa at the Department of Materials Science, University of Milan-Bicocca, where he works on the growth of crystalline organic films by organic molecular beam epitaxy, as well as their characterization and integration in optoelectronic devices (e.g., solar cells, OLEDs, transistors).
