Fabrication of 3D Photonic Crystals of Non-Magnetic Ellipsoids with Different Aspect Ratio

Article Preview

Abstract:

This paper introduces a method of preparation of photonic crystals with non-magnetic ellipsoid as building blocks. Under the condition of above its glass-transition temperature, monodispersed polystyrene (PS) spheres with the diameter of 260 nm and 360 nm were respectively elastic stretched by applying external force with different values to get different ellipsoids with different aspect ratios. The assembly procedure was carried out by applying the vertical deposition self-assembly method in a magnetic field under the guidance of magnetic fluids. In this paper, We report the crystalline structure with long range order.
