Abstract
An article including a stack of layers including a high refractive index layer and a low refractive index layer; wherein at least one layer of the stack includes a wavelength selective absorbing material; and wherein the stack of layers has a transparent region with an edge at a wavelength in which light is absorbed by the wavelength selective absorbing material, and a reflection band with an edge at a wavelength in which light is reflected is disclosed. Compositions and optical devices including the article are also disclosed. Additionally, there is disclosed a method of making the article, the composition, and the optical device.
Claims18
An opaque article, comprising:
- a stack of layers including a high refractive index layer and a low refractive index layer;
- wherein at least one layer of the stack includes a wavelength selective absorbing material;
- and
- wherein the stack of layers has a transparent region with an edge at a wavelength in which light is absorbed by the wavelength selective absorbing material, and a reflection band with an edge at a wavelength in which light is reflected by the wavelength selective absorbing material,
- wherein the stack does not include a layer of metal.
A method of making an article, comprising:
- depositing onto a substrate a stack of layers including a high refractive index layer and a low refractive index layer;
- wherein at least one layer of the stack includes a wavelength selective absorbing material;
- and
- wherein the stack of layers has a transparent region with an edge at a wavelength in which light is absorbed by the wavelength selective absorbing material, and a reflection band with an edge at a wavelength in which light is reflected,
- wherein the stack does not include a layer of metal;
- and
- wherein the article is opaque.
