Morphology‐Controlled Growth of Large‐Area Two‐Dimensional Ordered Pore Arrays

Abstract

A solution‐dipping template strategy for large‐area synthesis of morphology‐controlled, ordered pore arrays is reported. The morphology of the pore array can easily be controlled by concentration of the precursor solution and treatment conditions. With decrease of the concentration from a high level to a very low level nanostructured complex (pore–hole, and pore–particle) arrays, through‐pore arrays, and even ring arrays can, in turn, be obtained. The pore size is adjustable over a large range by changing the diameter of the template's latex spheres. This synthesis route is universal and can be used for various metals, semiconductors and compounds on any substrate. Such structures may be useful in applications such as energy storage or conversion, especially in integrated next‐generation nanophotonics devices, and biomolecular labeling and identification.

Morphological and Structural Control of Organic Monolayer Colloidal Crystal Based on Plasma Etching and Its Application in Fabrication of Ordered Gold Nanostructured Arrays

“…This transferability greatly extends the application of the colloidal crystals as the template since it could be used for the fabrication of micro/nanostructure arrays on any desired substrates. Further, due to the surface tension of the water or aqueous solution and the difference in the wettability between the glass substrate and the PS monolayer colloidal crystals, if we put the glass slide with the PS colloidal monolayer into water in a cup, the monolayer could be stripped off from the glass and float to the surface of the water [21]. Thus the as-prepared PS colloidal monolayer could have a good transferability and be transferred from the glass to any other desired substrates including silicon, silica, mica, copper grid in transmission electron microscope (TEM), and even the other hydrophobic and curved surfaces.…”

“…Among these, colloidal lithography is an inexpensive, flexible, and efficient method for fabrication of periodically arranged nanostructured arrays on a large scale by using the mono-, or bi-layer organic colloidal crystals as templates, due to their interstitial geometry. The organic monolayer colloidal crystals are usually prepared based on the principle of colloidal self-assembly [17][18][19][20][21][22][23][24]. There have been many routes developed to fabricate the colloidal crystals by self-assembling, such as the spin-coating method [21], dip-coating method [22] and gas/liquid interface self-assembly [23,24].…”

Fabrication and Photo-Detecting Performance of 2D ZnO Inverse Opal Films

“…To date, 2D IOs with various chemical compositions, including Ag, In 2 O 3 , ZnO, CeO 2 , Fe 2 O 3 , etc. have been successfully achieved through this method [5,16,17]. However, there still remain some problems to be solved.…”

Flexible Fabrication of Microarrays of Microwells

“…Several templating methods, based on self-assembly, have been used to create patterned substrates with sub-micron features. This includes the use of ordered arrays of colloidal particles, [19] microporous materials, [20,21] polymers with rod-coil architecture [22] or honeycomb structures, [23] self-organized surfactants, [24] and microphase-separated block copolymers.
