Abstract
There is provided an optical structure. The optical structure includes a light source. The optical structure also includes an organic light management film having an index of refraction of less than 1.7 disposed above the light source, and a transparent inorganic film having an index of refraction of greater than 1.7 disposed adjacent the organic light management film. A optical device is also provided including the organic light management film and the transparent inorganic film. A method of forming the optical structure is also provided. The method includes depositing the transparent inorganic film under vacuum.
