Abstract
Various optical device applications of surface plasmon (SP) resonance have been reported, in particular, we have discovered that plasmonics can significantly improve the emission efficiencies, and applicable to high-efficiency light-emitting devices. In order to develop efficient plasmonic LEDs at a practical level, tuning the SP resonance wavelength is one of the most important issues as well as device development. We present a new plasmonic metamaterial based on random nanostructures that can be fabricated easily, inexpensively, and over a large area by a bottom-up approach and enable tuning of the SP resonance in the deep ultraviolet and near infrared wavelength regions.
