Synthesis of tailor-made colloidal semiconductor heterostructures

摘要: The field of colloidal nanocrystal synthesis has progressed rapidly to the point where spherical colloids diverse sizes and compositions are commercially available or can be synthesized with minimal synthetic training. As quantum dots work their way into a greater array technologies, it become increasingly important maximize uniformity these nanoscale structures efficiency associated photophysical processes. Anisotropic nanocrystals confined heterostructures offer even customization tunability specific electronic photonic properties compared counterparts. However, access more advanced is less well understood, existing approaches often challenging execute replicate. This feature article provides an account various bottom-up top-down methods that have been developed prepare complex highlights progress made in preparation semiconductor heterostructures. From this survey methods, becomes clear seeded assembly heterostructure architectures combines many advantages both enable greatest potential control over diversity new, customizable added functionality.
