Selective growth of ZnO nanorods on pre-coated ZnO buffer layer

Synthesis and characterization of well-aligned Zn1−xMgxO nanorods and film by metal organic chemical vapor deposition

“…There is only one ultraviolet (UV) luminescence can be observed in each spectrum. The UV emission is assigned to the near-band-edge (NBE) emission, which originates from the free exciton emission and its replicas [30][31][32]. The UV luminescence shifts to shorter wavelength as the increase of Mg content, which suggests that the realization of the band gap engineering in Zn 1Àx Mg x O nanostructures.…”

Structural and optical properties of ZnO nanosaws

“…As the reaction process proceeded by repeating the above-mentioned processes, the condensed ZnO would continuously deposit on the nucleation sites to form the ZnO nanoribbons. Finally, it is known that [0 0 0 1] is the fastest growth direction along one side of ZnO nanostructures as reported in the combstructures [11][12][13]15] that is responsible for the formation of ZnO nanosaws. Fig.…”

“…Synthesis of ZnO nanosaws was achieved in a simple vapor transport process [15]. First, a very thin layer of Au was deposited on a (1 0 0)-silicon substrate.…”

Photoluminescence Study of the Influence of Additive Ammonium Hydroxide in Hydrothermally Grown ZnO Nanowires

“…The strong and narrow UV emission peak, centered at 3.24 eV for all cases, results from merging of the various exciton-related emission near the band-edge, including recombination of free excitons and its longitudinal optical (LO)-phonon replicas, [33] free-to-neutral acceptor transitions, [34] and donor-acceptor pair recombination, [35] depending on the local lattice configuration and the presence of defects. [36][37][38] The strong and narrow UV emission peak, centered at 3.24 eV for all cases, can be assigned to the donor-acceptor transition. From the Figure 2a, we can also observe a broad visible level emission that expands from green to orange color wavelength.…”
