    Abstract: A method of synthesizing LiFePO4 compounds and analogs thereof for use in secondary electrodes involves mixing the starting materials and polymerizing the mixture into a gel. The gel form allows thorough milling and mixing of the reagents and results in a smaller and more uniform particle size in the resultant electrode formed and a well crystallized structure based on the X-ray diffraction pattern.

    Abstract: A semiconductor color image sensor comprises: an array of semiconductor photo-sensors (CMOS or CCD) and a color filter array comprising an array of red, green and blue filter elements in which each filter element is associated with a respective one of the photo-sensors. The sensor further comprises a phosphor (photo-luminescent) material associated with each of the blue filter elements and configured to absorb blue light and re-emit light of a longer wavelength range which is then incident on the photo-sensor associated with the blue filter element. Preferably the phosphor material is selected such that light of the longer wavelength range substantially matches the spectral response of the photo-sensor. The image sensor can further comprise an array of micro-lenses for focusing light onto the photo-sensors of the image sensor, wherein each micro-lens is associated with a respective one of the photo-sensors.

    Abstract: Novel green phosphors are disclosed having the comprise silicate-based compounds having the formula (Sr,A1)x(Si,A2)(O,A3)2+x:Eu2+, where A1 is at least one divalent cation (a 2+ ion) including Mg, Ca, Ba, or Zn, or a combination of 1+ and 3+ cations; A2 is a 3+, 4+, or 5+ cation, including at least one of B, Al, Ga, C, Ge, N, and P; A3 is a 1−, 2−, or 3− anion, including F, Cl, Br, and S; and x is any value between 1.5 and 2.5, both inclusive. The formula is written to indicate that the A1 cation replaces Sr; the A2 cation replaces Si, and the A3 anion replaces O. These green phosphors are configured to emit visible light having a peak emission wavelength greater than about 480 nm. They have applications in green illumination systems, red-green-blue backlighting systems, white LEDs, and plasma display panels (PDPs).

    Abstract: Disclosed herein are cerium doped, garnet phosphors emitting in the yellow region of the spectrum, and having the general formula (Y,A)3(Al,B)5(O,C)12:Ce3+, where A is Tb, Gd, Sm, La, Sr, Ba, Ca, and/or Mg, and substitutes for Y, B is Si, Ge, B, P, and/or Ga, and substitutes for Al, and C is F, Cl, N, and/or S, where C substitutes for O. Relative to a solid-state-reaction method, the instant co-precipitation methods provide a more homogeneous mixing environment to enhance the distribution of the Ce3+ activator in the YAG matrix. Such a uniform distribution has the benefit of an increased emission intensity. The primary particle size of the as-prepared phosphor is about 200 nm, with a narrow distribution.
