TL;DR: A new ligand capping strategy utilizing common and inexpensive long-chain zwitterionic molecules such as 3-(N,N-dimethyloctadecylammonio)propanesulfonate is proposed, resulting in much improved chemical durability and allows for the isolation of clean NCs with high photoluminescence quantum yields of above 90% after four rounds of precipitation/redispersion.

TL;DR: This work rationalizes the typical observation of a degraded luminescence upon aging or the luminescent recovery upon postsynthesis surface treatments and proposes a strategy for healing the surface trap states and for improving the colloidal stability by the combined treatment with didodecyldimethylammonium bromid and lead bromide.

TL;DR: In this paper, the effect of size, shape, and halide composition on the electronic structure of PNCs was analyzed with density functional theory, and it was shown that the PNC crystalline core exhibits an orthorhombic structure.

TL;DR: This work indicates that CdSe nanoplatelets constitute a unique nanocrystal model system to establish a comprehensive description of midgap trap states, which includes their structural, chemical, and electronic properties.

TL;DR: In this article, the defect formation energies of interstitial, vacancy, and antisite defects in different regions of the nanocrystal (center, surface center, and surface edge) were computed using density functional theory.
