摘要: In this paper, we report on the first successful attempt of chemical vapor deposition (CVD) synthesis well-aligned single-crystalline ZnO nanotube arrays Mo wire mesh. According to detailed morphology and composition analyses, a rational growth model is proposed illustrate process hollow nanotubes. Metastable Zn-rich ZnOx nanorods formed in early stage are believed play vital role towards formation configuration. addition, also successfully fabricate ZnO/ZnS ZnO/CdS core/shell by simply depositing ZnS CdS pre-fabricated Despite existence large lattice mismatch, grown layers somewhat show an epitaxial orientation relationship with inner ZnO, that is, [0001]ZnS or CdS//[0001]ZnO (10-10)ZnS CdS//(10-10)ZnO. Further, room temperature cathodoluminescence (CL) characterization indicates after surface decoration, ZnO-based heterostructures distinguished optical properties. Quenching 67.2% 99.7% near-band-gap (NBE) emission observed ZnO/ZnS, respectively. Efficient charge separation resulting from type-II band configuration considered be responsible for variation Our method may represent powerful platform creation nanotubes tunable
