A generalized approach to photon avalanche upconversion in luminescent nanocrystals
Artiom Skripka, Minji Lee, Xiao Qi +7
Photon avalanching nanoparticles (ANPs) exhibit extremely nonlinear upconverted emission valuable for sub-diffraction imaging, nanoscale sensing, and optical computing. Avalanching…
Indefinite and Bidirectional Near Infrared Nanocrystal Photoswitching
Changhwan Lee, Emma Z. Xu, Kevin W. C. Kwock +14
Materials whose luminescence can be switched by optical stimulation drive technologies ranging from superresolution imaging1-4, nanophotonics5, and optical data storage6-8, to targ…
Giant nonlinear optical responses from photon avalanching nanoparticles
Changhwan Lee, Emma Xu, Yawei Liu +10
Avalanche phenomena leverage steeply nonlinear dynamics to generate disproportionately high responses from small perturbations and are found in a multitude of events and materials,…
