    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 ...

    Persistent luminescence mechanism of tantalite phosphors 

    Noto, Luyanda Lunga (University of the Free State, 2014-11)
    Pr3+ ion doped ZnTa2O6, SrTa2O6, CaTa2O6 and ZnTaGaO5 phosphors, which display persistent luminescence were prepared by solid state chemical reaction at 1200 oC for 4 hours. A ZnTa2O6:Pr3+ phosphor that resembled an ...
