Paper Abstract

We propose a fully bottom-up process to fabricate photonic polycrystalline over a large area at a low cost. By combining self-assembled polystyrene nanospheres and the oblique deposition technique, periodic arrays of nanospherical crown shells are obtained as a template. Non-close-packed nanopillar arrays are successfully fabricated by oblique-angle deposition on the template. The resulting nanopillar arrays exhibit some transmittance minima, which are understood in terms of the photonic band modes. Because the process proposed in this paper has advantages to obtain the photonic polycrystalline over a large area at a low cost, it can be applied to produce thermal infrared emitters with wavelength and directional tunabilities.
