Optical nonlinearities in excess of 500 through sublattice reconstruction
Nature, Published online: 18 June 2025; doi:10.1038/s41586-025-09164-yA strategy for engineering photon-avalanche nanoparticles is proposed such that they exhibit an unprecedentedly strong nonlinear optical response and their emissions scale by more than 500th power of the pump intensity.
