Method of making thin film structures and compositions thereof

摘要

This invention is directed to a method of modifying the refractive index of multilayer thin films structure comprising high refractive and low refractive index layers, where the high refractive and low refractive index layers are of the same material, the method comprises a) depositing a first layer of film of a refractive index on a substrate; b) depositing a second layer of film having a different refractive index onto the first layer of film; and c) depositing a third layer of film having a different refractive index from the second layer of film onto the second layer of film, and compositions thereof. In certain embodiments, this multilayer thin film structure of this invention is directed to decorative applications.

1. A method of making a thin film structure comprising alternating high refractive and low refractive index layers, the method comprising:
a) depositing a first layer of film on a substrate, the first layer having a high refractive index, wherein the refractive index is greater than 2.0; b) depositing a second layer of film onto the first layer of film, wherein the second layer of film is a material modified to have a different refractive index from the unmodified material, the second layer having a low refractive index, wherein the ratio of the low refractive index to the refractive index of the first layer is no more than 0.46; and c) depositing a third layer of film onto the second layer of film, the third layer having a high refractive index, wherein the refractive index is greater than 2.0, wherein the layers are of the same material.
