Understanding the Nanocrystal Innovation

The newly discovered nanocrystals, composed of potassium, chlorine, and lead, and doped with neodymium, exhibit a unique property called intrinsic optical bistability. This characteristic allows the nanocrystals to maintain two stable states - bright or dark - under the same laser excitation conditions 1

Dr. Artiom Skripka, assistant professor at OSU College of Science, explains the phenomenon:

"If the crystals are dark to start with, we need a higher laser power to switch them on and observe emission, but once they emit, they remain emitting and we can observe their emission at lower laser powers than we needed to switch them on initially" 2
