Characterization of Gd2O2S: Tb³+ phosphor powder and thin films
(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 ...
Luminescent properties of Y2SiO5:Ce thin films
(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 ...
Luminescent properties of synthesized PbS nanoparticle phosphors
(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 ...
