Title:
MOLDED NANOPARTICLE PHOSPHOR FOR LIGHT EMITTING APPLICATIONS
Document Type and Number:
WIPO Patent Application WO/2013/108125
Kind Code:
A3
Abstract:
A molded nanoparticle phosphor for light emitting applications is fabricated by converting a suspension of nanoparticles in a matrix material precursor into a molded nanoparticle phosphor. The matrix material can be any material in which the nanoparticles are dispersible and which is moldable. The molded nanoparticle phosphor can be formed from the matrix material precursor/nanoparticle suspension using any molding technique, such as polymerization molding, contact molding, extrusion molding, injection molding, for example. Once molded, the molded nanoparticle phosphor can be coated with a gas barrier material, for example, a polymer, metal oxide, metal nitride or a glass. The barrier-coated molded nanoparticle phosphor can be utilized in a light- emitting device, such as an LED. For example, the phosphor can be incorporated into the packaging of a standard solid state LED and used to down-convert a portion of the emission of the solid state LED emitter.
