The present invention relates to high-purity quantum dot-fullerene dimers with controllable linker length and the process of fabricating the same. More particularly, this invention relates to the design, synthesis, and application of high-purity quantum dot-fullerene dimers by applying a novel stepwise surface assembly procedure that ensures the formation of conjugates due to steric repulsion effects between the quantum dots.
