Inorganic layer light-emitting device |
摘要 |
There is provided an inorganic layer light-emitting device including: a light-emitting layer including an emission body made of an inorganic material; and a metal-based particle assembly layer being a layer consisting of a particle assembly including 30 or more metal-based particles separated from each other and disposed in two-dimensions, said metal-based particles having an average particle diameter in a range of from 200 to 1600 nm, an average height in a range of from 55 to 500 nm, and an aspect ratio in a range of from 1 to 8, and said metal-based particles that compose said metal-based particle assembly layer are disposed such that an average distance between adjacent metal-based particles is in a range of from 1 to 150 nm. The inorganic layer light-emitting device exhibits high luminous efficiency through emission enhancement and improvement in light extraction efficiency. |

1. An inorganic layer light-emitting device comprising:
a light-emitting layer including an emission body made of an inorganic material; a metal-based particle assembly layer being a layer consisting of a particle assembly including 30 or more metal-based particles separated from each other and disposed in two-dimensions, said metal-based particles having an average particle diameter in a range of from 200 to 1600 nm, an average height in a range of from 55 to 500 nm, and an aspect ratio, as defined by a ratio of said average particle diameter to said average height, in a range of from 1 to 8, said metal-based particles that compose said metal-based particle assembly layer being disposed such that an average distance between adjacent metal-based particles is in a range of from 1 to 150 nm. |
