Method for producing a translucent substrate as well as methods to control between Rayleigh scattering and Mie scattering method for producing an organic LED element, the scattering properties of light scattered by the scattering layer

摘要

Forming a scattering layer on a transparent substrate, a step of the scattering layer, placing a first electrode on the first electrode, a method for producing an organic LED element is mounted and the organic light-emitting layer a step of, in the organic light emitting layer, and a step of installing a second electrode, wherein the scattering layer comprises a matrix material made of glass, and a ceramic filler dispersed in the matrix material , then D and (μm) average particle size of the ceramic filler, and the (nm) λ the wavelength of the light generated from the organic light emitting layer, the absolute of the difference between the refractive index of the ceramic filler and the refractive index of the matrix material of the scattering layer When it is assumed that Δn values, suppress at the focus wavelength region the frequency dependence of the scattering intensity of the light that is scattered by the scattering _layer, D ≧ 3 × D _0, however, ceramic filler and the matrix material, D ₀ = case of improving the scattering intensity in the short wavelength side of light are chosen to satisfy in the noted wavelength region λ / (2π × Δn),, are scattered by the scattering layer, in the noted wavelength region, D and characterized in that it is selected so as to meet at the noted wavelength area _0, D.
