. . . . . . "Aligned coaxial nanocables were grown on Si substrates by a vapor-deposition technique. The lengths of thenanocables increased as the distance between the substrate and the source decreased. The nanocables werecharacterized as homogeneously crystallized shells of about 25 nm thick, diameters of about 100 nm, andround top ends. It was found that the shell emits an intense middle-ultraviolet about 300 nm at room temperature.This emission was attributed to the thin double-layer structure in the Zn\u2212Zn2SiO4 core\u2212shell nanocablewhere the Zn2SiO4 shell has the potential to serve as more ideal luminophors. The results demonstrated thatthe nanocable density could be changed by altering nucleation density at the steps on the substrate surface.The unique growth manner described herein provides a new technique for the homogeneous crystallizationof Zn\u2212Zn2SiO4 core\u2212shell nanocables." . . . .
