Two-dimensional CdSe-based nanoplatelets : their heterostructures, doping, photophysical properties, and applications

In the past decade, colloidal quantum wells, also known as 2-D semiconductor nanoplatelets (NPLs), have been added to the colloidal nanocrystal (NC) family. Through the unique control of the thickness with monolayer precision, these novel materials exhibit strong 1-D quantum confinement that offers...
