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…
Freeze-frame approach for robust single-molecule tip-enhnaced Raman spectroscopy at room temperature
Mingu Kang, Hyunwoo Kim, Elham Oleiki +7
A quantitative single-molecule tip-enhanced Raman spectroscopy (TERS) study at room temperature remained a challenge due to the rapid structural dynamics of molecules exposed to ai…
Conformational heterogeneity of molecules physisorbed on a gold surface at room temperature
Mingu Kang, Hyunwoo Kim, Elham Oleiki +8
A quantitative single-molecule tip-enhanced Raman spectroscopy (TERS) study at room temperature remained a challenge due to the rapid structural dynamics of molecules exposed to ai…
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,…
