SCNCs with different dimensionalities and structures. Each dimensionality category illustrates different structures of SCNCs. The TEM image for 0D shows CdSe‐core CdS/Zn_0.5Cd_0.5S/ZnS‐multishell NCs (reprinted from Ref. 37 with permission). The TEM image for quasi‐1D (q‐1D) shows the nanorod‐in‐rod structure of CdSe‐in‐CdS NCs (reprinted from Ref. 38 with permission). TEM image for 2D presents CdSe core nanoplatelets (reprinted from Ref. 39 with permission). The left TEM image of mixed dimensionalities shows double heterojunction CdS nanorods with CdSe/ZnS core–shell tips (reprinted from Ref. 40 with permission). The right STEM image of mixed dimensionalities shows elemental mapping of CdSe/Cd_1−xZn_xSe seeded nanorods with a graded shell; the upper semicircle is an overlay of Zn and Cd spatial distributions, which demonstrates the graded‐shell structure, while the bottom semicircle is an overlay of Zn and Se spatial distributions, which demonstrates the seeded‐rod structure (reprinted from Ref. 41 with permission). All scale bars correspond to 20 nm.
