Figure 1

Transmission electron microscopy (TEM) images and optical properties of CdSe/CdS core/shell nanocrystals with different geometries. TEM images for CdSe/CdS core/shell a) dots (wz-CdSe core/wz-CdS shell), b) rods (wz-CdSe core/wz-CdS rod shell), c) tetrapods (zb-CdSe core/wz-CdS arms). Corresponding ensemble absorption (blue) and fluorescence (orange) spectra for CdSe/CdS d) dots, e) rods, f) tetrapods. The blue x40 and x5 traces are provided for clear visualization of the exciton absorption peak. All scale bars 20 nm.
