Preparation and properties of long afterglow CaAl₂O₄ phosphors activated by rare earth metal ions
(University of the Free State, 2011-11)
This work comprises of several aspects of calcium-aluminate phosphor activated with rare earth metal ions i.e. (CaAl2O4:Eu2+, Nd3+, and Dy3+). In particular the luminescent and structural properties of the long afterglow ...
Red emission of Praseodymium ions (Pr ³⁺)
(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 and characterization of long afterglow phosphors (SrAl2O4:Ce³+, SrAl2O4:Tb³+, CaAlxOy:Tb³+, Y3Al5O12:Eu³+) using solution combustion method
(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 ...
