Plasmonic noble metal nanodisks with regular (triangular or hexagonal) shapes have been epitaxially formed on ZnO nanorods' (0002) surfaces. The composite material's crystal structures, epitaxial relationships between metal nanodisks, and ZnO host crystals were fully investigated. The effects from metal nanodisks on lasing characteristics of two types of(More)
Au and Ag hybrid hexagonal nanodisks were synthesized on ZnO nanorods' (0002) surface via a new two-step deposition-annealing method. The structural, compositional, as well as optical investigations were carried out systematically to find out the nanodisks' formation mechanism and optical enhancement effect. It was shown that the core-shell Au/Ag nanodisk(More)
A green-light-emitting diode device was fabricated based on a p-type Sb-doped ZnO segments/Cd-alloyed ZnO/n-type ZnO film/heteronanowires array structure. The structures and chemical components of the heteronanowire sample were studied by energy dispersive spectrometer, x-ray photoelectron spectrometer, etc, from which the statuses of Cd and Sb in the(More)
The electronic structures at the interface of aluminum tris(8-hydroxyquinoline) (Alq3)/Al2O3/Al have been determined by ultraviolet photoemission spectroscopy measurements and compared to similar measurements of the Alq3/Al interface. In the Alq3/Al2O3/Al study, shift of the highest occupied molecular orbital level of the Alq3 layer was observed when(More)
