Metal ions to control the morphology of semiconductor nanoparticles: Copper selenide nanocubes Li, Wenhua Zamani, Reza Ibáñez, Maria ; https://orcid.org/0000-0001-5013-2843 Cadavid, Doris Shavel, Alexey Morante, Joan Arbiol, Jordi Cabot, Andreu Morphology is a key parameter in the design of novel nanocrystals and nanomaterials with controlled functional properties. Here, we demonstrate the potential of foreign metal ions to tune the morphology of colloidal semiconductor nanoparticles. We illustrate the underlying mechanism by preparing copper selenide nanocubes in the presence of Al ions. We further characterize the plasmonic properties of the obtained nanocrystals and demonstrate their potential as a platform to produce cubic nanoparticles with different composition by cation exchange. © 2013 American Chemical Society.
