Glass substrates which realize high out‐coupling efficiency OLEDs were developed. A scattering layer whose matrix was made of high refractive index glass was formed on a glass substrate. The out‐coupling efficiency of an OLED using this substrate is 1.8 times higher compared with an OLED using an untreated glass substrate.

Monolayers of n-pentanephosphonic or n-tetradecanephosponic acids are obtained by immersion of mechanically polished zinc substrates in solutions of either absolute ethanol or a mixture of water/ethanol (25/75%). X-ray photoelectron spectroscopy, contact angle and scanning Kelvin probe measurements indicate that both compounds lead to good-quality monolayers and the longer alkyl chain n-tetradecanephosponic acid molecules form the more densely packed films. However, the best films (n-tetradecanephosponic acids) do not show any resistance to electrochemical assays (polarization curves in NaOH and NaCl).
