Best Practices in Nanocrystal Synthesis and Characterization

Conspectus Colloidal nanocrystals exhibit quantum-mechanical phenomena inaccessible in bulk matter, and their properties can be tuned via chemically manipulating their composition, size, shape, and surface chemistry. Decades of development have produced a remarkable synthetic lib...

Concurrent Etching and Exchange Reactions During the Partial Replacement of Cu+ with Ni2+ in Copper Sulfide Nanorods

Abstract Partially exchanging a fraction of the Cu+ cations in copper sulfide nanoparticles with other cations can produce heterostructured derivatives that incorporate multiple metal sulfides. Cation exchange reactions can compete with etching processes, where the exchanging cat...
