    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 ...

    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 ...

    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 ...

    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 ...

    Luminescent properties of synthesized PbS nanoparticle phosphors 

    Dhlamini, Mokhotjwa Simon (University of the Free State, 2008-08)
    Luminescent lead sulphide (PbS) nanoparticles embedded in an amorphous silica (SiO2) matrix were synthesized at room temperature by a sol-gel process. The prepared nanocomposite materials were crushed into powders and ...

    Degradation of ZnS:Cu,Au,Al phosphor powder and thin films under prolonged electron bombardment 

    Hillie, Kenneth Thembela (University of the Free State, 2001-10)
    Auger electron spectroscopy (AES) and cathodoluminescence (CL), both excited by the same electron beam, were used to monitor changes in surface composition and luminous efficiency during electron bombardment. ZnS:Cu,Al,Au ...

    Luminescence from lanthanide ions and the effect of co-doping in silica and other hosts 

    Ahmed, Hassan Abdelhalim Abdallah Seed (University of the Free State, 2012-07)
    Amorphous silica powders doped with lanthanide ions were synthesised by the sol-gel method and their cathodoluminescence (CL) and photoluminescence (PL) emissions were compared. Interesting differences depending on the ...
