Available as a custom synthesized Europium doped RED phoshor for LED applications. In addition this material is available as a custom synthesized SrxCa1-xS.Eu red phosphor for a wavelength shifted RED phosphor for LED applications. Lorad has developed proprietary methods for synthesizing maximum efficiency strontium sulfide and calcium sulfide phosphors with a particle size <5 microns. These phosphors are more efficient than mechanically milled and re-activated phosphors, and the process is more efficient and cost-effective than particle fractionation methods.
