    Abstract: There is herein described a composite oxynitride ceramic converter comprising a first phase of a triclinic SrSi 2 O 2 N 2 :Eu phosphor with a second phase of a hexagonal Sr 3 Si 6 N 4 O 9 :Eu phosphor. By utilizing two oxynitride phases in the converter, a dense oxynitride ceramic converter with a high quantum efficiency (QE) may be achieved. The composite oxynitride ceramic converter is preferably paired with a blue-emitting LED produce a green-emitting LED light source.

    Abstract: Methods for producing wavelength converters are described. The methods include sintering a mixture consisting essentially of first particles and second particles to form a sintered article. In embodiments the first particles consist essentially of particles of β-SiAlON or precursors thereof, and the second particles consist essentially one or more sintering aids or precursors thereof. In embodiments the sintered article has a density that is greater than or equal to about 90% of a theoretical bulk density of the mixture, and is configured to convert primary light incident thereon to secondary light, wherein the secondary light exhibits a peak with a full width half maximum of greater than 0 to about 60 nanometers (nm) within a wavelength range of about 495 nm to about 600 nm.

    Abstract: Wavelength converters including coarse particles/grains of a red nitride phosphor are disclosed. In some embodiments the red nitride phosphor is a (Ca,Sr,Ba) 2 Si 5 N 8 : Eu phosphor with a D50 grain size or a D50 particle size that is ≥ 5 microns. The red nitride phosphor may be encapsulated within an organic matrix or present in an inorganic matrix. In the latter case, the inorganic matrix may include fine grains with a D50 grain size
