Analysis of the structure, particle morphology and photoluminescent properties of ZnS:Mn2+ nanoparticulate phosphors

Author: Raleaooa, PV ; Roodt, A ; Mhlongo, Gugu H ; Motaung, David E ; Ntwaeaborwa, OM Date: Jan 2018 The 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
Effect of P on the electrochemical activity of carbon supported Pt-Ru alloy catalyst for methanol oxidation.

Author: Mohlala, M ; Modibedi, Remegia M ; Mathe, Mahlanyane K Date: Nov 2007 In 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 ...

Pulsed laser deposited KY3F10: Ho3+ thin films: Influence of target to substrate

Author: Debelo, NG ; Dejene, FB ; Roro, Kittessa T Date: Apr 2017 The 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 ...

Sensitizing effects of ZnO quantum dots on red-emitting Pr3+-doped SiO2 phosphor

Author: Mbule, PS ; Mhlongo, Gugu H ; Pitale, SS ; Swart, HC ; Ntwaeaborwa, OM Date: May 2012 In 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
