    Characterization of Gd2O2S: Tb³+ phosphor powder and thin films 

    Dolo, Jappie Jafta (University of the Free State, 2011-06)
    Under Ultra violet (UV), cathode-ray and X-ray excitation, terbium activated rare earth oxysulphide (Gd2O2S:Tb3+) phosphors shows bright green luminescence. Due to its superior luminescent performance, Gd2O2S:Tb3+ phosphor ...

    Synthesis and characterization of down−conversion nanophosphors 

    Tshabalala, Kamohelo George (University of the Free State, 2014-10)
    Luminescent zinc aluminate (ZnAl2O4) nanoparticles, crystalline–low quartz and amorphous silica powders were incorporated with Ce3+ and Tb3+ ions. These powders were successfully synthesized by the solution combustion and ...

    Characterization of Y3(Al,Ga)5O12:Ce3+ phosphor thin films prepared by pulsed laser deposition 

    Dlamini, Sipho Thapo Solomon (University of the Free State, 2013-11)
    The morphological and luminescent properties of Y3(Al,Ga)5O12:Ce3+ powder phosphor were investigated. Scanning Electron Microscopy (SEM) revealed the phosphor’s agglomerated particles with a size ranging from 0.4μm to ...

    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 ...

    Synthesis and characterization of MBxOy:Eu (M = Ca, Sr, Ba) phosphors and TiO2 semiconductor for application in luminescence and energy materials 

    Sithole, Thokozane Moses (University of the Free State, 2014-11)
    MBxOy:Eu (M = Ca, Sr, Ba) phosphors with different Ca:B /Sr:B /Ba:B molar ratio and with constant Eu concentration have been synthesized by a solution combustion method at initial reaction temperature of 5000C for 15 ...

    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 ...

    Synthesis and characterization of long afterglow phosphors (SrAl2O4:Ce³+, SrAl2O4:Tb³+, CaAlxOy:Tb³+, Y3Al5O12:Eu³+) using solution combustion method 

    Foka, Kewele Emily (University of the Free State, 2011-11)
    This work consists of several aspects of phosphor materials. Strontium, calcium and yttrium aluminate doped with rare earth (Ce, Tb and Eu) have been synthesized by solution combustion method using urea as a fuel for ...

    Thermal, structural and luminescent properties of long after-glow MAlxOy:Eu²+,Dy³+ (M: Sr, Ba) phosphors 

    Bem, Barasa Daniel (University of the Free State, 2010-11)
    The optimization of properties for new and potentially useful materials becomes a continuous and sometimes a lifelong process if future applications are anticipated. Research on luminescent materials is a good example of ...

    Synthesis, characterization and luminescent mechanism of ZnS:Mn²+ nanophosphor 

    Biggs, Mart-Mari (University of the Free State, 2009-11-30)
    ZnS:Mn2+ is commercially used in field emission displays (FEDs) and biological imaging of brain tumors. This study was done to determine the luminescent mechanism of both bulk and nano sized ZnS:Mn2+. Luminescent zinc ...
