Dual control : Hybrid silica–nanocrystal–organic dye superstructures comprising fluorescein isothiocyanate (FITC)‐doped silica cores, embedded CdTe quantum dots, and an outer silica shell display well‐resolved dual fluorescence emission. Multicolor encoding fluorescent probes are generated by modulating the fluorescence intensity ratio of the dual emission by a simple post‐encoding strategy (see picture).
