  • A TEM and STEM investigation of Cu-Ag nanomaterials

    Mar 01 2000 · It is well documented that low-temperature ball-milling can force immiscible elements e.g. Cu and Ag into solid solution. A slight increase of the milling temperature however results in a two- or even three-phase coexistence 1 . This coexistence is likely to take place at a nanometric scale since ball-milling results in the formation of grains with a size in the 10 nm range.

  • CHARACTERISTICS OF THERMOLUMINESCENCE LiF Mg Cu Ag

    A nanophosphor of LiF Mg Cu Ag was prepared by planetary ball milling for the first time in the laboratory. The size and shape of the nanophosphor were confirmed by XRD and SEM which showed that it was cubic in shape and 53 nm in size. The thermoluminescence (TL) characteristics of this nanophosphor were then investigated.
