| 英文摘要 | Arrays of vertically well-aligned zno nanorod-nanowall junctions have been synthesized on an undoped zno-coated silicon substrate by a carbothermal reduction and vapour phase transport method. x-ray diffraction (xrd) and scanning electron microscopy (sem) show that the nanostructures are well-oriented with the c-axis perpendicular to the substrate. the room temperature photoluminescence (pl) spectrum of the as-prepared zno nanostructure reveals a dominant near-band-edge (nbe) emission peak and a weak deep level (dl) emission, which demonstrates its good optical properties. temperature-dependent pl spectra show that both the intensity of nbe and dl emissions increased with decreasing temperature. the nbe emission at 3.27 ev is identified to originate from the radiative free exciton recombination. the possible growth mechanism of zno nanorod-nanowall junctions is also proposed. |
