    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 camera-based x-ray digital image detectors that contain an assembly of a scintillator screen, a wide-angle optical lens or fisheye lens, and a digital image sensor. Images formed by x-ray radiation on the scintillator screen are projected onto a much smaller area image sensor through a fisheye or super-wide-angle optical lens, hence forming a highly distorted image thereon. Transparent lead-contained glasses or plastics are utilized to shield image sensor from x-ray damage. Imaging distortion and light falloff caused by the lens optics are corrected by software algorithms. Sub-millimeter resolution may be achieved with reduced design complexity and substantially lower manufacturing costs.

    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.
