Perspective highlights advances in photon avalanching nanoparticles' energy transfer and unique properties, suggesting new applications.
Photon Avalanching Nanoparticles This cover illustrates the energy transfer network driving burst emission in photon avalanche (PA). In their Perspective (DOI: 10.1002/adfm.202531980), Changhwan Lee and co-workers review achievements in PA's extreme nonlinearity and sensitivity. They provide analytical frameworks to interpret PA photophysics and propose directions to unlock the full potential of these nanoparticles.
