摘要： The lumen maintenance of fluorescent lamps containing yttrium vanadate phosphors is markedly improved by the presence of a protective oxide layer for the phosphor. The protective oxide layer is produced by evaporating aluminum isopropoxide, in a vacuum, over phorphor particles forming a continuous aluminum isopropoxide over the phosphor particles. The isopropoxide coating is subsequently oxidized by lehring the phosphor at a temperature from about 500.degree. C. to 625.degree. C. forming an alumina coating on the phosphor particles.

摘要： A fluorescent lamp comprises at least one layer of a four-component phosphor blend for producing visible illumination having a white color. The quad-phosphor blend comprising a first and second red-emitting phosphor component with each red-emitting phosphor component having different visible emission spectrum principally in the 590 to 630 nm wavelength range. A third blue-emitting phosphor component has an emission spectrum principally in the 430 to 490 nm wavelength range. A fourth no-rare-earth green-emitting phosphor component has an emission spectrum principally in the 500 to 570 nm wavelength range. The relative proportions of the phosphor components are such that an enhanced color rendering index is produced as compared to tri-component blends formed from only three of the phosphor components.

摘要： An efficient green emitting phosphor results from the coactivation of yttrium fluoride with gadolinium and erbium. The excitation energy absorbed by the Gd.sup.3+ centers is transferred non-radiatively to minority Er.sup.3+ centers, whose emission produces green light when excited by 275 nanometer or 378 nanometer radiation.

摘要： Phosphors and a method for producing yellow-emitting tin-manganese coactivated calcium fluorophosphate phosphors having improved brightness comprises the steps of blending a powder mixture including the phosphates, carbonates, fluorides and oxides of calcium, tin, and manganese together with an ammonium salt, and firing the mixture at a temperature of between about 1100.degree. C. and about 1300.degree. C. for a period sufficient to produce a luminescent composition. The presence of an ammonium compound in the initial powder blend promotes the proper atmosphere during the firing step to insure the incorporation of proper levels of tin and manganese ions in the final phosphor.
