25. A method for depositing a barrier coating, comprising the steps of:
-
providing at least one surface for deposition; depositing reaction or recombination products of reacting species on the surface; changing the compositions of the reactants fed into the reactor chamber during the deposition to form a compositionally organic-inorganic coating;
said coating comprising at least one substantially organic zone and at least one substantially inorganic zone;performing refractive index modification of the at least one inorganic zone by varying the precursor gas composition, said refractive index of the inorganic zone being adjusted to provide a substantially uniform refractive index along an axis of light transmission through said barrier coating. - View Dependent Claims (26, 27, 28, 29, 30)
