Dependence of photoluminescence (PL) emission intensity on Eu3+ and ZnO concentrations in Y2O3:Eu3+ and ZnO·Y2O3:Eu3+ nanophosphors

Author: Mhlongo, Gugu H ; Dhlamini, MS ; Swart, HC ; Ntwaeaborwa, OM ; Hillie, KT Date: Aug 2011 Y2O3:Eu3+ and ZnO·Y2O3:Eu3+ nanophosphor powders with different concentrations of Eu3+ ions were synthesized by a sol–gel method and their luminescence properties were investigated. The red photoluminescence (PL) from Eu3+ ions with the main ... Read more
Effects of Ce3+ concentration, beam voltage and current on the cathodoluminescence intensity of SiO2: Pr3+–Ce3+ nanophosphor

Author: Mhlongo, Gugu H ; Ntwaeaborwa, OM ; Dhlamini, MS ; Swart, HC ; Hillie, KT Date: Feb 2011 SiO2:Pr3+–Ce3+ phosphor powders were successfully prepared using a sol–gel process. The concentration of Pr3+ was fixed at 0.2 mol% while that of Ce3+ was varied in the range of 0.2–2 mol%. High resolution transmission electron microscopy ... Read more
Energy transfer mechanism in the hydroentaglement nonwoven process

Author: Moyo, D ; Anadjiwala, R Date: 01 Sep 2010 Nonwoven fabrics are engineered assemblies of natural and man-made fibres bonded together mechanically, thermally, chemically or by a combination of these techniques. The nonwoven industry has a huge growth potential compared to weaving and ... Read more
Harvesting sunlight energy: a biophysics approach

Author: Smit, Jacoba E ; Grobler, AF ; Sparrow, RW Date: Apr 2011 The most efficient light harvesting and energy transfer systems are found in nature as part of the photosynthesis process. In the photosynthetic system light energy is absorbed by antenna chlorophylls and this energy is then passed onto a ... Read more
Light activated bionanodevices

Author: Sparrow, RW Date: 27 Feb 2006 The aim of this research is to develop a device that will move a rod in 8 nm controllable steps. The researchers are utilising the biological principles and materials of photosynthetic light (energy) harvesting and transfer, ATPsynthase, ATP ... Read more
