    摘要： A fluorescent lamp providing improved maintenance and brightness includes an alkaline earth halophosphate (Cool-White) phosphor, e.g. a calcium halophosphate phosphor, having a continuous protective bilayer coating of alumina surrounding silica surrounding the phosphor particles. The lamp may be a high color rendition fluorescent lamp in which a first layer of alkaline earth halophosphate phosphor coats an inner surface of the lamp envelope, and a second layer of phosphor overlies the first layer of phosphor. The second layer of phosphor is a mixture of red, blue and green emitting phosphors, at least one of these being a zinc silicate phosphor. Each of the alkaline earth halophosphate and zinc silicate phosphors have a bilayer coating in which a coating of alumina surrounds a coating of silica which surrounds the phosphor.

    摘要： A method for producing manganese activated zinc silicate phosphor wherein the individual phosphor particles are surrounded with a non-particulate, conformal aluminum oxide coating is disclosed. The method comprises dry blending a mixture of components consisting essentially of zinc oxide, silicic acid, a source of manganese, ammonium chloride, ammonium fluoride, tungstic oxide, and silica, wherein the Zn+Mn/Si mole ratio is from about 1.95 to about 2.02, wherein the silica is colloidal and has a surface area of from about 50 to about 410 m.sup.2 per gram, and wherein the colloidal silica makes up from about 0.01% to about 1.0% by weight of the mixture; firing the resulting dry blend of components in a nitrogen atmosphere at a temperature of from about 1200.degree. C. to about 1300.degree. C. for a sufficient time to produce the phosphor; milling the resulting phosphor for a period of time of from about 60 minutes to about 120 minutes; firing the resulting milled phosphor in air at a temperature of from about 1175.degree. C. to about 1275.degree. C. for a sufficient time to diffuse the tungsten and manganese to the surfaces of the phosphor particles; applying a non-particulate, conformal aluminum oxide coating to the outer surface of individual particles of the phosphor while the phosphor particles are suspended in a fluid bed having a midpoint temperature between 400.degree. and 480.degree. C., the aluminum oxide coating being formed by a chemical vapor deposition reaction involving oxidation of trimethyl aluminum; and annealing the aluminum oxide coated phosphor for a period of time from 4-16 hours at a temperature between 750.degree. and 800.degree. C.

    摘要： A method for preparing a specific zinc orthosilicate phosphor particle having a nonparticulate, conformal aluminum oxide coating wherein all of a manganese activator is present as manganese (II) and occupies zinc (II) sites includes the steps of blending a zinc source, a manganese (II) source, a silicon source, and a tungsten source in amounts in accordance with said formula with an amount of up to about 2 weight percent NH.sub.4 Cl and up to about 0.2 weight percent NH.sub.4 F to form a relatively uniform admixture, firing the mixture in a closed container under an inert non-oxidizing atmosphere to promote retention of manganese in the plus two valance state whereby oxidation of manganese to a higher valence state is avoided and conditions promote larger particle size formation; milling and washing the phosphor in an aqueous citric acid solution to remove unreacted manganese; rinsing, drying and sieving the dried phosphor; and depositing a continuous, nonparticulate, conformal aluminum oxide coating on the dried phosphor particle.

    摘要： A fluorescent lamp based on a phosphor excited by a molecular discharge is described. The fluorescent lamp comprises a fluorescent lamp coated with a manganese doped magnesium aluminate phosphor on the inside surface of the lamp envelope. The fluorescent lamp contains corrosion resistant filamentary electron emitting electrodes. The fluorescent lamp produces a plasma which emits 206 nm radiation from the molecular discharge of the iodine containing molecular vapors and inert gas fill which in turn excites the phosphor to emit visible light.
