| 英文摘要 | zno complex 3d nano-structures have been self-organized on al2o3 (0 0 0 1) substrate by laser molecular beam epitaxy (l-mbe). it is shown by afm morphology that the structure is composed of id quantum dot chains (qdcs) and larger nano-islands at the nodes of qdcs. the formation mechanism of the nano-structure is also investigated. xrd results indicate that the nano-structure is highly c-axis oriented, with the aligned in-plane oriented domains. time-integrated photoluminescence (tipl) of the sample shows obvious blue-shift and broadening of the near band-edge (nbe) emission at room temperature, which are related to the quantum confinement effects. time-resolved pl (trpl) result shows bi-exponential decay behavior of zno qdcs, with a fast decay time of 38.21 ps and a low decay time of 138.19ps, respectively, which is considered to be originated from the interdot coupling made by coherent emission and reabsorption of the photons in qdcs.
