Estimating the term…
There is provided a composite thin film-holding substrate in which a composite thin film (4) comprising a filler (2) having a refractive index lower than that of a substrate (1) and a binder (3) having a refractive index higher than that of the filler (2) is formed on a surface of the substrate (1). Light is efficiently scattered when passing through the composite thin film (3) which comprises the filler (2) and the binder (3) having different refractive indexes from each other. In addition, the refractive index of a composite thin film (4) comprising a filler (2) having a low refractive index is low. As a result, the discharge efficiency of light which passes through the composite thin film (4) from the substrate (1) to the external is improved.
A composite thin film-holding substrate which comprises a substrate and a composite thin film disposed on a surface of the substrate, wherein
A composite thin film-holding substrate which comprises a substrate and a composite thin film disposed on a surface of the substrate, wherein
A transparent and electrically conductive film-holding substrate comprising:
A surface light emitting device comprising a thin film of a fluorescent material, wherein the thin film of the fluorescent material is formed on a composite thin film of a composite thin film-holding substrate, the composite thin film-holding substrate comprising a substrate and a composite thin film disposed on a surface of the substrate, wherein the composite thin film comprises a filler and a binder, the filler is selected from the group consisting of fine aerogel fine particles, silica fine and hollow particles, and polymer fine and hollow particles, and the binder is selected from the group consisting of organic polymers and metal oxides, and wherein a refractive index of the filler (Nf) is lower than a refractive index of the binder (Nb) lower than a refractive index of the substrate (Ns), and the thin film of the fluorescent material comprises an organic or inorganic fluorescent material which is excited by an ultraviolet ray or electron ray to emit light.
