Seeing Is Believing: Scientists Visualize Record Exciton Diffusion Length

In modern optoelectronic devices, performance depends in part on the movement of excitons. Researchers have now created a new perovskite nanocrystal system and taken direct visualizations of the movement of an exciton from crystal to crystal over a record 200 nanometers, much longer than the previous record. This paves the way for new commercial application.
