WIPO Patent Application WO/2016/208645
Kind Code:
A1
Abstract:
This optical device is provided with a metal thin film layer 12, a nano-periodic structure 13 which is formed from a dielectric material and which comprises nanostructures 13a formed periodically in a two-dimensional arrangement on the metal thin film layer 12, and a wavelength conversion layer 14 which is formed on the metal thin film layer 12 so as to cover the nanostructures 13a, and which, irradiated from an excitation light source, emits light of a wavelength different from that of the excitation light, wherein the metal thin film layer 12 and the wavelength conversion layer 14 are partially in contact.
