Synthetic opal and photonic crystal

摘要: A colloidal suspension of particles is rapidly self-assembled with a minimum number defects into densely packed array on substrate under simultaneous sedimentation and annealing forces. The may be ordered as an opal structure. Optionally, the synthesized structure incorporate electrolyte used sacrificial form for micromolding inverse exhibit photonic band gap. necking between adjusted after micromolding. Furthermore, shell alter physical properties, such protecting thermally stimulated gap device. These low cost methods allow more applications to become commercially viable.
