Abstract
An ink composition is provided. The composition includes a binder material and at least one narrow band emission phosphor being uniformly dispersed throughout the composition, wherein the narrow band emission phosphor has a D50 particle size from about 0.1 μm to about 15 μm and is selected from the group consisting of a green-emitting U6+-containing phosphor, a green-emitting Mn2+-containing phosphor, a red-emitting phosphor based on complex fluoride materials activated by Mn4+, and a mixture thereof. A device is also provided.
Claims27
An ink composition comprising a binder material and at least one narrow band emission phosphor being uniformly dispersed throughout the composition, the narrow band emission phosphor having a D50 particle size from about 0.1 μm to about 15 μm and is selected from the group consisting of a green-emitting U6+-containing phosphor, a green-emitting Mn2+-containing phosphor, a red-emitting phosphor based on complex fluoride materials activated by Mn4+, and a mixture thereof, wherein the ink composition is deposited on a substrate.
A device comprising an LED light source optically coupled and/or radiationally connected to an ink composition comprising a binder material and at least one narrow band emission phosphor being uniformly dispersed throughout the composition, the narrow band emission phosphor having a D50 particle size from about 0.1 μm to about 15 μm and is selected from the group consisting of a green-emitting U6+-containing phosphor, a green-emitting Mn2+-containing phosphor, a red-emitting phosphor based on complex fluoride materials activated by Mn4+, and a mixture thereof, wherein the ink composition is deposited on a substrate and is cured or dried.
A method comprising depositing an ink composition on a substrate, wherein the ink composition comprises a binder material and at least one narrow band emission phosphor being uniformly dispersed throughout the composition, the narrow band emission phosphor having a D50 particle size from about 0.1 μm to about 15 μm and is selected from the group consisting of a green-emitting U6+-containing phosphor, a green-emitting Mn2+-containing phosphor, a red-emitting phosphor based on complex fluoride materials activated by Me, and a mixture thereof.
