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 ...
Simulating the formation of Pt nanostructures utilizing molecular dynamic calculations
(University of the Free State, 2014)
Platinum (Pt) is an important catalyst for applications such as catalytic converters. In this thesis the formation of platinum nanoparticles was investigated by means of simulations. For the first part of the thesis a ...
Novel ZnO nanostructures: synthesis, growth mechanism, and applications
(University of the Free State (Qwaqwa Campus), 2014-12)
The ZnO nanostructures were successfully synthesized by chemical bath deposition method (CBD) to study the influence of parameters such as reaction temperature, time, precursor concentration and the annealing temperature ...
