Abstract
Three-dimensional (3D) ordered nanoparticle microstructures possess multidimensional effects than 2D structures, which bring novel features for the application of biotechnology, magnetic device, catalysis and optoelectronic. However, complexity to manipulate ordered microstructures with additional dimensions triggered by long distance interactions between nanoparticles or external force from fluid, electric or magnetic field, thus leading to random and uncontrollable displacement of nanoparticle. In the present work, well-controlled cross-section of ordered 3D microstructures is proposed on assembly of nanoparticles, which achieved by manipulating capillary bridges. Experimental results reveal that the formation of various cross-sections dependents on concentration (C) and diameter of nanoparticle. Due to the building block and solvents has no special request, this technique can be extend to other materials. Owing to the controllable morphology, we can manipulate the waveguiding distance of 3D architectures. Thus, our research highlight the opportunity for creating cross section controlled 3D architectures with potential applications in optoelectronics.
Highlights
We demonstrate that 3D architectures with controllable cross section can be utilized in manipulating the optical waveguiding distance
Capillary bridge method employed in this work is described in the material and method section. 3D linear microstructures with three varying cross-sections including top and lateral view of dumbbell (Fig. 1a), trapezoid (Fig. 1b) and triangle (Fig. 1c) was observed through scanning electron microscope (SEM) under various concentrations
We suggest a reasonable explanation for various cross sections
Summary
Spatial arrangement of nanoparticle possess significant effect for the micro- or nanodevices due to the nanoparticle with distinct property could interact with each other over a long distance, which could bring novel effects for the devices. The extension from 2D to 3D has the capability in tailoring material properties and developing equipment with multidimensional effects.[34,35] To date, several strategies have been developed to allow 3D patterning of nanoparticles
