Author:Raleaooa, PV; Roodt, A; Mhlongo, Gugu H; Motaung, David E; Ntwaeaborwa, OMDate:Jan 2018The structure, particle morphology and photoluminescent properties of n(sup2+) doped ZnS nanoparticles are reported. The X-ray powder diffraction studies showed that incorporation of Mn(sup2+) did not cause any change to the crystallized cubic ...Read more
Author:Mohlala, M; Modibedi, Remegia M; Mathe, Mahlanyane KDate:Nov 2007In polymer electrolyte membrane fuel cell (PEMFC), platinum is recognized to be the most active metal for methanol oxidation, however there is a strong CO adsorption tendency, which blocks the surface for further methanol adsorption and leads ...Read more
Author:Debelo, NG; Dejene, FB; Roro, Kittessa TDate:Apr 2017The influence of target to substrate distance (dts) on the structural, morphological and photoluminescence (PL) properties of commercially obtained KY3F10 : Ho3+ phosphor thin films prepared by pulsed laser deposition is investigated for dts ...Read more
Author:Mbule, PS; Mhlongo, Gugu H; Pitale, SS; Swart, HC; Ntwaeaborwa, OMDate:May 2012In this study, red cathodoluminescence (CL) ( emission=614 nm) was observed from Pr3+ ions in a glassy (amorphous) SiO2 host. This emission was enhanced considerably when ZnO quantum dots (QDs) were incorporated in the SiO2:Pr3+ suggesting ...Read more
