Abstract
An inorganic coating may be applied to bond optically scattering particles or components. Optically scattering particles bonded via the inorganic coating may form a three dimensional film which can receive a light emission, convert, and emit the light emission with one or more changed properties. The inorganic coating may be deposited using a low-pressure deposition technique such as an atomic layer deposition (ALD) technique. Two or more components, such as an LED and a ceramic phosphor layer may be bonded together by depositing an inorganic coating using the ALD technique.
Claims30
A method comprising:
- depositing a plurality of optically scattering particles onto a component;
- and
- depositing an inorganic coating onto the plurality of optically scattering particles using a low-pressure deposition technique.
A device comprising:
- a plurality of optically scattering particles on a component;
- an inorganic coating deposited onto the plurality of optically scattering particles using a low-pressure deposition technique;
- a first three dimensional film, wherein a first optically scattering particle is bonded to a second optically scattering particle by the inorganic coating.
A method comprising:
- treating a surface of a first component, wherein the treating is one of roughing and adding grooves;
- depositing an inorganic coating onto the surface of the first component using a low-pressure deposition technique;
- and
- bonding the first component with a second component, wherein the inorganic coating facilitates the bonding of the first component with the second component.
