| Research Abstract |
In this research project, we have successfully fabricated the aluminum nano-pillar array structure on the glass substrate using nano-coating lithography technique. We have already confirmed experimentally that the fabricated Al nano-pillar array could support the surface plasmon resonance at the ultraviolet wavelength region. We also found that a few nanometer anisotropy of chemically synthesized gold nanoparticles induces blue shift of plasmonic resonance. The unprecedented optical phenomenon that the Al thin film with nanometer hole array structure showed higher reflectivity than the flat Al thin film was discovered.
