Using near-infrared light, researchers have darkened and brightened lanthanide-doped nanoparticles over 1000 times with no degradation.

In 2021, lanthanide-doped nanoparticles made waves—or rather, an avalanche—when Changwan Lee, then a PhD student in Jim Schuck’s lab at Columbia Engineering, set off an extreme light-producing chain reaction from ultrasmall crystals developed at the Molecular Foundry at Berkeley Lab.

A research team, affiliated with South Korea's Ulsan National Institute of Science and Technology (UNIST) has made a significant breakthrough in uncovering the potential of ultra-photostable avalanching nanoparticles (ANP).
