Fabrication of 2D Composite Photonic Crystal Structure on Air-Water Interface |
| 초록 |
In this investigation, we developed a technique to fabricate 2-dimensional crystalline composite colloidal monolayers using the suspension composed of Poly(methyl methacrylate) (PMMA) microspheres and Titanium oxide (TiO2) nanoparticles at air/water interface. The compactly floated composite arrays of PMMA/TiO2 on water surface were successfully transferred to a solid substrate. Our method can provide the highly reflective 2D photonic crystal owing to the high index nano-particles beneath PMMA microsphere array. Moreover, we can produce TiO2 inverse opal layer which has 'egg plate' structure upon calcination of template particles. We also strengthened the TiO2 inverse opal structure by additional spin coating of TiO2 nanoparticles. This intriguing conformation is looked forward to be utilized for various photonic applications. |
