Luminescence investigations of CaS:Eu2+ powder and pulsed laser deposited thin films for application in light emitting diodes
(University of the Free State, 2015-06)
The main objective of this thesis was to investigate the luminescent properties of commercial CaS:Eu2+ powder and pulsed laser deposited thin films for application in light emitting diodes. X-ray diffraction (XRD), X-ray ...
Tunable multicolour emission from dysprosium-doped mixed rare-earths oxyorthosilicate nanophosphors for application in ultraviolet-pumped multicolour and white light emitting diodes
(University of the Free State, 2015-02)
Phosphors have many uses today in applications such as electronic information displays, solid state lighting, solar cells, advertising and theft prevention. By using urea-assisted solution combustion method, we prepared ...
Luminescence properties of Y2O3:Bi3+ as powder and thin film phosphor for solar cell application
(University of the Free State, 2015-07)
The luminescent properties of the bismuth doped yttrium oxide (Y2-xO3:Bix) phosphor material was investigated as a powder and as thin films for possible application as a down-conversion material for solar cells. The goal ...
