Flower-like MnS spheres on the surface of MnS nanowire arrays were synthesized via a hydrothermal treatment using anodized aluminum oxide(AAO) as the template. The as-prepared samples were characterized by FESEM, TEM, HRTEM, SAED, and XRD. The results show that MnS flower-like spheres are grown on MnS nanowire arrays. The diameter of the MnS nanowires is 70 similar to 80 inn corresponding to the pore diameter of the AAO template used, and flower-like MnS spheres are consisted of single-crystal nanowire. The number of flower-like AinS spheres increases with the reduction of the pore length of the AAO template. The room-temperature PL spectrum shows a strong emission peak at about 420 nm corresponding to the MnS band edge emission. Furthermore, the growth mechanism for the MnS nanostructure has been proposed. AAO template and the air bladders formed via thiourea decomposition to H(2)S gas under hydrothermal treatment may play an important role in the formation of MnS flower-like spheres sitting on MnS nanowire arrays.
