Moving from the visible to the infrared: Developing high quality nanocrystals

Awarded the 2023 Nobel Prize in Chemistry, quantum dots have a wide variety of applications ranging from displays and LED lights to chemical reaction catalysis and bioimaging. These semiconductor nanocrystals are so small—on the order of nanometers—that their properties—such as color—are size-dependent, and they start to exhibit quantum properties. This technology has been well developed, but only in the visible spectrum, leaving untapped opportunities for technologies in both the ultraviolet and infrared regions of the electromagnetic spectrum.
