Optical Properties of the 3-D Composite Photonic Crystals Prepared by Modified Dip-Coating and Coating First Method

Article Preview

3-D composite photonic crystals were fabricated on ITO substrates and slide glass substrates by two different methods, modified dip-coating and coating first method. It was found that there were lots of line defects existing in the composite films fabricated by dip-coating method but few existing in the composite films fabricated by coating first method. The reflectance spectra were measured by UV-vis spectrometry and revealed that all the fabricated photonic crystals exhibit a photonic band gap in the normal direction. The optical properties of the core-shell structure strongly depended on the intrinsic defects in the films.
