Controlling the Emission Properties of Quantum Rods via Multiscale 3D Ordered Organization

Table 1

Influence of the QR ordering on the maximum intensity wavelength () and on the decay of fluorescence emission for 18 and 40 nm long CdSe/CdS QRs (see Figure 3 for detailed experimental conditions and graphical data). Deconvolution of fluorescence emission decay curves using three exponentials yields (see Fig. S3), for each condition and each species, three preexponential factors, , and three lifetimes, . designed the average lifetime of the . “Water” corresponds to measurements on QRs in aqueous solution whereas all the other conditions refer to dried states. In “Heap,” they lay aggregated with a local liquid crystal order, and finally in “Pattern,” they are organized in microstructured supracrystals.
