Development of an optical thermometry system for phosphor materials
(University of the Free State, 2017-10)
English: This study is focussed on the development of a system that was used to investigate the emission of thermographic phosphors at various temperatures. The photoluminescence (PL) system at the Department of Physics ...
Preparation and characterization of powders and pulsed laser deposited thin films of rare-earths doped oxyorthosilicates
(University of the Free State, 2017-11)
Today, phosphor materials have found many technological applications such as in electronic information display, advertising, solid-state lighting, solar cells, theft prevention, medicine, data storage, quality control, ...
Theoretical and experimental study of core-shell structured ZnO/ZnS and growth mechanism of un-doped and doped ZnO nanomaterials
(University of the Free State (Qwaqwa Campus), 2017-12)
There is currently widespread interest among researchers in ZnO-ZnS coreshell nanorods as electrodes in prototype solar cells. ZnS has been proposed as a suit- able inorganic sensitizer to ZnO because ZnO and ZnS when in ...
