Improved sensitivity and selectivity of pristine zinc oxide nanostructures to H2S gas: Detailed study on the synthesis reaction time

Author: Motaung, David E ; Mhlongo, Gugu H ; Bolokang, Amogelang S ; Dhonge, Baban P ; Swart, HC ; Ray, Suprakas S Date: Nov 2016 The gas sensing properties of ZnO nanostructures synthesized at various reaction times are reported in this study. The response of ZnO nanostructures to H(sub2), NH(sub3), H(sub2)S and NO(sub2) gases was investigated at different operating ... Read more
Induced ferromagnetic and gas sensing properties in ZnO-nanostructures by altering defect concentration of oxygen and zinc vacancies

Author: Motaung, DE ; Makgwane, Peter R ; Ray, SS Date: Jan 2015 We report on the effect of the synthesis reaction-time on the structural, optical, magnetic and sensing properties of ZnO-nanostructures. Electron paramagnetic resonance and photoluminescence analyses reveal that singly ionized oxygen vacancies ... Read more
Metal oxide nanostructures-containing organic polymer hybrid solarcells: Optimization of processing parameters on cell performance

Author: Motaung, DE ; Makgwane, Peter R ; Ray, SS Date: Jul 2015 We report the chemical synthesis of various ZnO nanostructures and TiO2 nanoparticles and their dispersion in a P3HT matrix. The photoluminescence studies revealed improved charge transport in the active layer of the optimized TiO2 nanoparticles ... Read more
