Abstract

An optical device featuring high efficiency and luminance is provided. The optical device includes carrier generation layer that causes fluorescence to occur with incident light, plasmon excitation layer that excites first surface plasmons with said fluorescence, carrier generation layer being laminated on carrier generation layer, and exit layer that extracts the first surface plasmons or light that occurs on an opposite surface of carrier generation layer contact surface of plasmon excitation layer to the outside. Carrier generation layer contains metal particles that excite second surface plasmons with said incident light.
