Noble metal nanostructures, especially gold nanocrystals, have attracted intensive interest
due to their rich plasmonic properties and enormous potential technological applications.
The preparation process of gold nanocrystals can strongly affect their plasmonic properties
and therefore their performances in various applications. Chemically synthesized colloidal
gold nanocrystals are usually employed in biomedical fields, while lithographically
fabricated ones are highly preferred for constructing optical meta-structures. A detailed …
