Large lateral sized two-dimensional Cu2-xS nanoplates formed by Ostwald ripening
Large lateral sized two-dimensional (2-D) colloidal nanocrystals with a uniform thickness are highly desired but difficult to prepare. Herein we demonstrated that colloidal copper (I) sulfide (Cu1.75S) nanoplates with an large lateral dimension, i.e. 200 nm to 1 µm, can be successfully produced from...

| Summary: | Large lateral sized two-dimensional (2-D) colloidal nanocrystals with a uniform thickness are highly desired but difficult to prepare. Herein we demonstrated that colloidal copper (I) sulfide (Cu1.75S) nanoplates with an large lateral dimension, i.e. 200 nm to 1 µm, can be successfully produced from small Cu2-xS nanoplates via an Ostwald ripening process. The availability of the large lateral sized Cu2-xS nanoplates produced through this approach not only sheds light on the construction of 2-D nanostructures of other systems but also provides a platform for the cation exchange reaction to generate a variety of 2-D nanoplates with large lateral dimensions. |
