"lattice with pronounced local crystal field distortions enables >500 magnitude of nonlinear (abrupt, avalanche-like) emission output surge once light excitation intensity surpasses critical threshold... ideal for ultrasensitive detection/ advanced imaging... orders of magnitude more sensitive... spatially distinct nonlinear emission patterns within individual nanocrystals, allowing imaging with resolution beyond physical dimensions of emitters themselves... super-resolution imaging, highly sensitive chemical/ bio -sensing."
