Nanoparticles exist far from the equilibrium state due to their high surface energy.
Nanoparticles are therefore extremely unstable and easily change themselves or react with …

Cation exchange is an age-old technique for the chemical conversion of liquids or extended
solids by place-exchanging the cations in an ionic material with a different set of cations. The …

The development of nanomaterials for next generation photonic, optoelectronic, and
catalytic applications requires a robust synthetic toolkit for systematically tuning composition …

The chemistry, material processing and fundamental understanding of colloidal
semiconductor nanocrystals (quantum dots) are advancing at an astounding rate, bringing …

Highly stable and luminescent InP/GaP/ZnS QDs with a maximum quantum yield of 85%
were synthesized by in situ method. The GaP shell rendered passivation of the surface and …

In recent years, microfluidic technologies have emerged as a powerful approach for the
advanced synthesis and rapid optimization of various solution‐processed nanomaterials …

Highly luminescent CuInS2/ZnS (CIS/ZnS) core/shell quantum dots with a quantum yield of
65% were synthesized by a cation exchange reaction. Similar sized CIS cores and CIS/ZnS …

The partial transformation of ionic nanocrystals through cation exchange has been used to
synthesize nanocrystal heterostructures. We demonstrate that the selectivity for cation …

We have investigated cation exchange reactions in copper selenide nanocrystals using two
different divalent ions as guest cations (Zn2+ and Cd2+) and comparing the reactivity of …
