“…As a new class of photoelectrode materials for photovoltaic devices, the well aligned one-dimensional ZnO nanostructures, such as nanorods (NRs) and nanowires (NWs), have been widely investigated as photoelectrodes for dye-sensitized solar cells (DSSCs), due to the large surface area to adsorb more sensitizer and the direct electrical pathway to ensure the rapid collection of carriers generated by optical excitations [1][2][3][4][5]. However, nanostructured metal oxide photoelectrodes, such as ZnO and TiO 2 , are facing the major limitation of poor visible light absorption.…”

“…Using the CBD technique, a number of different structures of ZnO films have been previously reported such as nanowires or nanorods 1–4, nanoflowers 3–6, nanobelts 7, nanocolumns or nanoplates 8, nanotetrapod 9, nanotube 10, and nanosheets 11–14. In this study, we report unique textures of ZnO films grown by CBD.…”

Phone: þ82 31 290 7251, Fax: þ82 31 290 7272The unique surface textures of zinc oxide (ZnO) films grown by chemical bath deposition were presented. Both the zinc concentration and ethanol content in the chemical bath were found to affect the surface texture of ZnO films significantly. At certain growth conditions, the commonly observed textures derived from ZnO hexagonal rods evolve into unique shell-like textures. The shell-like surface textures are entirely different from the common textures in that the shape of grains is not hexagonal but rather round. A possible mechanism for the shelllike texture growth was discussed.

“…Thus, 2D ZnO nanostructure materials show the performances of photoconductivity conversion devices, which is beneficial to optical information processing, laser protection, and signal conversion. ZnO films have been investigated intensively as transparent conductive films used in display, solar cell, and various optoelectronic devices. − After an initial period of nucleation and incubation, a crystallite will commonly develop into a 3D object with well-defined, low index crystallographic faces. − …”

Morphology-rich ZnO as a direct band gap II−VI semiconductor is a promising material for photonic, optical, and electronic devices. Nanostructured materials have provided a leading edge to the next-generation technology due to their distinguished performances and efficiencies for device fabrication. The nonlinear optical (NLO) properties and mechanisms dependent on the size and dimensionality of ZnO nanostructures remain to be elucidated. Herein, we begin to provide a comprehensive summary of the status of research activities in ZnO nanostructures, including their syntheses and potential applications, with an emphasis on multidimensional ZnO nanostructure based growth, properties, and applications. Density functional theory calculations confirmed the effect of ZnO size, morphology, and defect on the structure, work function, and charge density distribution of the electron band. Finite difference time domain simulation confirmed that the electric field, magnetic field, and Poynting vector of the ZnO system with the morphology changes were applied. Moreover, the ultrafast NLO and carrier dynamics of feature-rich ZnO nanostructures were studied. The effects of different experimental parameters on the morphology and linear and nonlinear excitation and radiation mechanisms of ZnO nanostructures were studied by constructing an electron transfer mechanism diagram and the Z-scan technique. The results show that the properties and properties of ZnO nanostructures can be regulated and controlled by the structure and morphology. The application and performance of feature-rich zinc oxide nanostructures in photoelectric functional devices are prospected, which will provide valuable references and guidance for related researchers.
