Among the various postsynthesis treatments of colloidal nanocrystals that have been
developed to date, transformations by cation exchange have recently emerged as an …

Colloidal semiconductor nanocrystals have attracted continuous worldwide interest over the
last three decades owing to their remarkable and unique size-and shape-, dependent …

We have synthesized atomically flat CdSe/CdTe core/crown nanoplatelets (NPLs) with
thicknesses of 3, 4, and 5 monolayers with fine control of the crown lateral dimensions. In …

We report a study of Zn2+ by Cd2+ cation exchange (CE) in colloidal ZnSe nanocrystals
(NCs). Our results reveal that CE in ZnSe NCs is a thermally activated isotropic process. The …

We review the progress in ion exchange in a variety of nanocrystal structures from the
earliest accounts dating back over two decades ago to the present day. In recent years the …

Over the past few years, colloidal copper chalcogenide nanocrystals (NCs) have emerged
as promising alternatives to conventional Cd and Pb chalcogenide NCs. Owing to their wide …

Heterostructures of metal chalcogenides have attracted immense attention due to their
enhanced charge transport, synergistic optoelectronic and catalytic properties. While …

The incorporation of copper dopants into II–VI colloidal nanocrystals (NCs) leads to the
introduction of intragap electronic states and the development of a new emission feature due …

Research on ultrathin nanomaterials is one of the fastest developing areas in contemporary
nanoscience. The field of ultrathin one-(1D) and two-dimensional (2D) colloidal nanocrystals …

The direct synthesis of heteronanocrystals (HNCs) combining different ternary
semiconductors is challenging and has not yet been successful. Here, we report a …
