Abstract: A method for preparing a laminate substrate for a light emitting device includes providing a glass substrate having a refraction index, at 550 nm, of between 1.45 and 1.65, coating a glass frit having a refractive index, at 550 nm, of at least 1.7 onto the glass substrate, firing the resulting frit coated glass substrate at a temperature above the Littleton temperature of the glass frit thereby forming a first high index enamel layer, coating a metal oxide layer onto the first high index enamel layer, and firing the resulting coated glass substrate at a temperature above the Littleton temperature of the glass frit, thereby making react the metal oxide with the underlying first high index enamel layer and forming a second high index enamel layer with a plurality of spherical voids embedded in the upper section of the second high index enamel layer near the interface with air.

Abstract: A layered structure suitable as a support for an organic light emitting device (OLED), includes a light-transmissive glass substrate, a diffusive internal extraction layer (IEL) with an outer layer made of a glass containing at least 30 weight % of Bi2O3, formed on one side of the light-transmissive glass substrate, and an acid-resistant barrier layer formed on the IEL. The acid-resistant barrier layer has a bilayer structure made of an ALD-deposited metal oxide layer, the metal oxide being selected from the group consisting of aluminum oxide (Al2O3), titanium oxide (TiO2), zirconium oxide (ZrO2) and hafnium oxide (HfO2), in contact with the IEL, and a sputter-deposited SiOxNy layer in contact with the ALD-deposited metal oxide layer.
