Particle Shape Control via Etching of Core@Shell Nanocrystals

“…3,6,[9][10][11] Control of nanocrystal shape is crucial to tailor the functionality of individual particles as well as to target collective phenomena in self-assembled superstructures. 6,[12][13][14][15][16][17][18][19] Multi-component nanocrystals with controlled shape were engineered for bioimaging, biomedical, diagnostics, energy storage, environmental remediation, and sensing applications. [20][21][22][23][24][25] In particular, the element composition modifies the sensitivity of metal nanocrystals by affecting the plasmonic properties and so the refractive index.…”

“…Manipulation of atomic bonds is an established means toward the design of chemical or physical properties of materials at the nanoscale. − The deformation of the crystalline lattice modifies the binding energy and the chemical activity and selectivity of metal nanocrystals. The lattice distortion of the nanocrystals is ruled by structural and microstructural features such as size, shape, and defects. ,,− Control of nanocrystal shape is crucial to tailor the functionality of individual particles as well as to target collective phenomena in self-assembled superstructures. ,− Multicomponent nanocrystals with controlled shape were engineered for bioimaging, biomedical, diagnostics, energy storage, environmental remediation, and sensing applications. − In particular, the element composition modifies the sensitivity of metal nanocrystals by affecting the plasmonic properties and the refractive index .
