| Research Abstract |
We have developed coating high quality opal crystal films, and investigated their potential engineering applications. By controlled growth for colloidal crystallization, it was possible to fabricate 300 square centimeter opal films with uniform thickness, ten micron meter or less, and high crystal quality. In the project, we have demonstrates the opal photonic crystal films are applied for following prospective applications. (1) Strain imaging for plastic deformation metal plate. Structure color change of opal film enables to detect strain of metal by naked eyes. (2) 1D photonic crystal film made of high refractive index material. A chalcogenide glass with inverse opal structure film was coated for cm scale area by a new process. (3) A new chemical sensing material for environmental research field. To detect a small mount of benzene in pure water (0.18mg/ml).
