    • The values of molar extinction coefficients of CdSe/CdS nanorods were determined as follows. First, a careful analysis of TEM images of both as-prepared and size-selected fractions of CdSe/CdS nanorods showed the absence of nucleation of new CdS nanocrystals upon growing the CdS shell if the molar ratio of Cd and S precursors was 1:3. This implies that the concentration of particles in the reaction mixture remains constant during the shell growth and is equal to the initial concentration of CdSe cores. This concentration can be easily estimated because the molar extinction coefficients of CdSe nanocrystals are known (Yu, W. W.; Qu, L.; Guo, W.; Peng, X. Chem. Mater. 2003, 15, 2854). Consequently, we measured the evolution of the absorption spectra of CdSe/CdS nanorods and calculated their molar extinction coefficients using the estimated concentration of nanocrystals and optical densities of crude solutions.
