“…Although the ZnO (002) peak dominated, weak ZnO (101), (102), and (103) peaks were observed clearly in the XRD pattern of sample 3, implying the poor c -axis orientation of ZnO nanostructures grown on dip-coated seed layer. From the XRD pattern of sample 1, we can see that ZnO (100), (002), (102), (110), and (103) peaks appear at about the same intensity, demonstrating the random orientation of ZnO nanostructures grown on the bare Si substrate [14,21]. Conclusions drawn from the XRD patterns are in high accordance with those drawn from earlier SEM results.…”

In this paper, controllable synthesis of various ZnO nanostructures was achieved via a simple and cost-effective hydrothermal process on the Si substrate. The morphology evolution of the ZnO nanostructures was well monitored by tuning hydrothermal growth parameters, such as the seed layer, solution concentration, reaction temperature, and surfactant. X-ray diffraction and photoluminescence measurements reveal that crystal quality and optical properties crucially depend on the morphology of the ZnO nanostructures. The ease of synthesis and convenience to tune morphology and optical properties bring this approach great potential for nanoscale applications.

“…fabrication method named as nanosphere lithography for the production of periodic particle array surfaces with nanometer-scale features. NSL was firstly reported by the research work of Hulteen and Van Duyne [17] and has been widely employed in the area of two-and three-dimensional (2D and 3D) micro/nanostructures patterning, such as quantum dots, nanowires, nanomesh, antireflection structure (ARS), and 3D inverse-opal photonic crystals [18][19][20][21][22][23]. Compared to those traditional sophisticated lithographic methods, NSL has shown a great many advantages that include a simple nanofabrication technique, an inexpensive route for the patterning of long-range periodic nanostructure arrays in a large scale area, and high throughput.…”

A single-monolayered hexagonal self-assembled photonic crystal (PC) pattern fabricated onto polyethylene terephthalate (PET) films by using simple nanosphere lithography (NSL) method has been demonstrated in this research work. The patterned nanostructures acted as a scattering medium to extract the trapped photons from substrate mode of optical-electronic device for improving the overall external quantum efficiency of the organic light-emitting diodes (OLEDs). With an optimum latex concentration, the distribution of self-assembled polystyrene (PS) nanosphere patterns on PET films can be easily controlled by adjusting the rotation speed of spin-coater. After attaching the PS nanosphere array brightness enhancement film (BEF) sheet as a photonic crystal pattern onto the device, the luminous intensity of OLEDs in the normal viewing direction is 161% higher than the one without any BEF attachment. The electroluminescent (EL) spectrum of OLEDs with PS patterned BEF attachment also showed minor color offset and superior color stabilization characteristics, and thus it possessed the potential applications in all kinds of display technology and solid-state optical-electronic devices.

This article presents a facile and generally applicable methodology for the morphology diversification of two-dimensional (2D) nanostructure arrays by modifying angle-resolved heterogeneous shadow mask (AR-HSM). Colloid spheres are used to prepare scalable well-organized monolayer film by self-assembly method and then etched in oxygen plasma to reduce size. Subsequently, the heterogeneous layer is generated by tilted metal deposition technique, then utilized as shadow mask in the substrate etching process, and finally removed by wet etching technique. As a result, the controllable fabrication of a series of complex morphologies, ranging from the crescent structure to the hoof-like structure and the stripes with apexes, is realized. The morphology of the nanostructure array is depend on the profile of the heterogeneous shadow mask (HSM) which is correlated to the incidence angle of the metal vapor. Therefore, a theoretical model is built for the prediction and design of the nanostructure morphology. This AR-HSM aided approach provides a novel and accessible route for the diversification of nanostructure morphology; and can be readily extended to other functional substrates which may be applied in photovoltaic devices or bio-chemical sensors.
