Investigation of the luminescent properties of metal quinolates (Mqx) for use in OLED devices
(University of the Free State, 2014-01)
Since Tang and VanSlyke developed the first organic light emitting diode (OLED) in the late 80’s using tris-(8-hydroxyquinoline) aluminium (Alq3) as both the emissive and electron transporting layer, a lot of research has ...
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 ...
