    Abstract: A coated phosphor may comprise: phosphor particles comprised of a phosphor with composition (M)(A)2S4: Eu, wherein: M is at least one of Mg, Ca, Sr and Ba; and A is at least one of Ga, Al, In, Y; a dense impermeable (pinhole-free) coating of an oxide material encapsulating individual ones of the phosphor particles. The coated phosphor is configured to satisfy one or more of the conditions: (1) under excitation by blue light, the reduction in photoluminescent intensity at the peak emission wavelength after 1,000 hours of aging at about 85° C. and about 85% relative humidity is no greater than about 30%; (2) the change in chromaticity coordinates CIE(y), ΔCIE y, after 1,000 hours of aging at about 85° C. and about 85% relative humidity is less than about 5×10−3; (3) said coated phosphor does not turn black when suspended in a 1 mol/L silver nitrate solution for at least two hours at 85° C.; (4) said coated phosphor does not turn black when suspended in a 1 mol/L silver nitrate solution for at least one day at 20° C.; and (5) said coated phosphor does not turn black when suspended in a 1 mol/L silver nitrate solution for at least 5 days at 20° C.

    Abstract: The teachings are generally directed to phosphors having combination coatings with multifunctional characteristics that increase the performance and/or reliability of the phosphor. The teachings include highly reliable phosphors having coatings that contain more than one inorganic component, more than one layer, more than one thicknesses, more than one combination of layers or thicknesses, a gradient-interface between components, a primer thickness or layer to inhibit or prevent leaching of phosphor components into the coatings, a sealant layer to inhibit or prevent entry of moisture or oxygen from the environment, a mixed composition layer as a sealant and multifunctional combination coatings.
