Paper Abstract

We report 3D photonic crystals of polystyrene micro-spheres and air spheres in Barium titanate Background with diameters between 220 and 1100 nm by filling the voids (between the polystyrene micro-spheres) with Barium titanate. The BaTiO3 was synthesized from a sol gel solution. The polystyrene is then removed by calcination. The pyrolysis at 550°C enables to make the right phase of BaTiO3. Scanning electron microscope and optical microscope confirm the quality of the samples. The structure strongly diffracts light and can be a step to photonic band gap materials.
