Synthesis and characterization of down−conversion nanophosphors
(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 ...
Sol-gel synthesis and characterization of MAl2O4 (M = Zn or Mg) spinels doped, co-doped and triply doped nano-phosphors
(University of the Free State (Qwaqwa Campus), 2014-12)
The luminescent and structural properties of the MAl2O4 (M = Zn, Mg) (which are thereafter referred as hosts) phosphors prepared by sol-gel methods at a relatively low temperature (~80 °C) are discussed. Zinc, magnesium ...
Synthesis and characterization of MBxOy:Eu (M = Ca, Sr, Ba) phosphors and TiO2 semiconductor for application in luminescence and energy materials
(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 ...
