One‐dimensional nanocomposite colloids are prepared by means of electrostatic self‐assembly of CdTe nanocrystals on both carbon nanotubes (CNTs) and silica‐coated CNTs (see Figure). The dense coverage of these linear nanoparticle assemblies minimizes the spacing between the nanocrystals, thereby facilitating efficient electronic and energy transfer along the nanotubes.
