Latest Patents

Jongmin Choi holds a patent titled "Passivation of nanocrystals tailored to different facets, and its application to optoelectronic devices." This patent describes a method for facet-selective passivation on each crystal facet of colloidal nanocrystals via a solution-phase ligand exchange process. The method provides highly-passivated and colloidally-stable nanocrystal inks. By addressing polar and non-polar facets separately, the strategy prevents deleterious nanocrystal aggregation in the colloid. The introduction of alkali metal organic complexes during metal halide conventional solution exchanges, such as Na·Ac, stabilizes and passivates the non-polar facets while polar facets are passivated through metal halides. This innovative approach leads to a significant decrease in nanocrystal aggregation and improves the photophysical properties of the resulting nanocrystal solid films.
