The fabrication and spectrum characteristic of high-organized 3D photonic crystal

Number controlled polystyrene(PS) opals were self-assembled 3D photonic crystal(PC).B₂O₃-P₂O₅-SiO₂(BPS) inverse opals were fabricated by capillary force infiltrating BPS and selecting removing the PS ball.Absorption and transmission spectrum indicated that photonic band gap(PBG) was blue shifted obviously.XRD shows that the BPO₄ crystal phase was increased with the temperature increasing,which might change the dielectric constant and should be paid attention for the PC usage.
