Chemistry researchers have taken a key step toward next-generation optical computing and memory with the discovery of luminescent nanocrystals that can be quickly toggled from light to dark and back ...
Previous examples of optical bistability suffered from serious drawbacks, such as depending on temperature changes that make it hard to prevent interference between neighbors. “Normally ...
Published in Nature Photonics ("Intrinsic optical bistability of photon avalanching nanocrystals"), the study by Skripka and collaborators at Lawrence Berkeley National Laboratory, Columbia University ...
