    Abstract: A method of separating a phosphor material from a starting mixture is disclosed. The separating includes dispersing the starting mixture in a liquid medium comprising a surfactant; and varying the pH to sediment a yttrium europium oxide (YEO) phosphor, lanthanum phosphate (LAP) phosphor, or both. Sedimenting the YEO phosphor includes adjusting the pH to less than about (3) and then increasing the pH to be in a range from about (5) to about (6). Sedimenting the LAP phosphor comprises adjusting the pH to greater than about (10) and then decreasing the pH to be in a range from about (8) to about (9).

    Abstract: A low-pressure discharge lamp includes, in an exemplary embodiment, a light-transmissive envelope, a fill-gas composition capable of sustaining a discharge sealed inside the light-transmissive envelope, and a phosphor composition at least partially disposed on an interior surface of the light-transmissive envelope. The phosphor composition is disposed on an interior surface of the light-transmissive envelope in a plurality of layers that include at least a basecoat phosphor layer and a topcoat phosphor layer. The basecoat phosphor layer includes at least one halophosphor and the topcoat phosphor layer includes a blend of at least two rare earth phosphors. The basecoat phosphor layer has a greater Color Rendering Index (CRI) value than the topcoat phosphor layer.

    Abstract: The present invention relates to a novel phosphor, which consists of oxynitride having good durability and which can emit variously colored light ranging from green light to yellow light when a blue LED or ultraviolet LED is used as an excitation source. According to the present invention, the phosphor is obtained by dissolving an activator in a host lattice, wherein the host lattice has a monoclinic crystal structure and is represented by the general formula: (Ca1-x M1x)a(La1-y M2y)bSicNdOe (0.5=b/a=7, 1.5=c/(a+b)=3.5, 1=d/c=1.8, 0.6=e/(a+b)=2, 0=x=0.5, 0=y=0.5), and the activator is at least one species selected from Mn, Ce, Pr, Nd, Sm, Eu, Gd, Dy, Tb, Ho, Er, Tm, and Yb. Here, M1 is at least one element selected from Ba, Mg, Sr, Mn, and Zn, and M2 is at least one element selected from Y, Lu, Sc, Gd, Tb, Ce, Nd, Sm, Dy, Ho, Er, Tm, Yb, Al, Ga, Ge, Sn, and In.

    Abstract: 本发明公开了一种低铕含量红色荧光粉的制备方法，包括将氧化钇铕粉体共沉淀分散于弱碱性溶液中；在搅拌条件下，将水溶性铕盐溶液加入上述弱碱性溶液中，使铕元素沉淀；将沉淀物洗涤烘干，800～1000℃灼烧1～小时，得到预烧粉体；将预烧粉体在1300～1500℃烧结2～4h，将烧结得到的固体研磨，洗涤烘干，得到红色荧光粉。本发明方法有效地提高了铕的利用率，减少了铕的用量。通过本发明方法制备的红色荧光粉，在不降低，或很少降低荧光粉发光性能的前提下，可大大减少铕的使用量，使得其整体成本降低约10%。
