Effect of dye on the band gap of 3D polystyrene photonic crystals

摘要

We report the synthesis of polystyrene (PS) nanospheres through emulsion polymerization and fabrication of three dimensional PS photonic crystals (PhCs) with good crystalline quality using vertical deposition method. The reflection and transmission spectral characteristics of the PhCs fabricated from the pure and dye doped PS nanospheres are compared.
