Nanocrystals are already used in millions of devices, including televisions, laptops and displays, and are considered key materials for the next generation of quantum, sensing and solar technologies. However, they have not yet fully realized their potential. One major reason is their inherent hetero geneity: A single solution contains billions of nanocrystals whose properties can differ substantially. Although these particles can be characterized, important quality parameters are typically accessible only as average values across the entire sample. ...read more read less
