    Red emission of Praseodymium ions (Pr ³⁺) 

    Noto, Luyanda Lunga (University of the Free State, 2011-11)
    English: Red glowing phosphors were prepared by adding Pr3+ ions as activators to several oxide host matrixes; CaTiO3, LaTaO4, YTaO4, and GdTaO4. The perovskite CaTiO3:Pr3+ compound is a phosphor that glows with a single ...

    Luminescent properties of Y2SiO5:Ce thin films 

    Coetsee, Elizabeth (University of the Free State, 2010-05)
    The luminescent properties of yttrium silicate doped with cerium (Y2SiO5:Ce) phosphor thin films were investigated. A detailed investigation (cathodoluminescence (CL), photoluminescence (PL) and Gaussian peak fits) was ...

    Investigation of the luminescent properties of metal quinolates (Mqx) for use in OLED devices 

    Duvenhage, Mart-Mari (University of the Free State, 2014-01)
    Since Tang and VanSlyke developed the first organic light emitting diode (OLED) in the late 80’s using tris-(8-hydroxyquinoline) aluminium (Alq3) as both the emissive and electron transporting layer, a lot of research has ...
