Author:Kabongo, GL; Mhlongo, Gugu H; Mothudi, BM; Hillie, KT; Swart, HC; Dhlamini, MSDate:2014In this work, the sol–gel method was used to prepare Ytterbium (Yb(sup3+)) doped ZnO nano-phosphors with different concentrations of Yb(sup3+) ions. Their structural, morphological, photoluminescence, electronic states and the chemical ...Read more
Author:Kabongo, GL; Mbule, PS; Mhlongo, Gugu H; Mothudi, BM; Dhlamini, MSDate:Jan 2020The fluorescence vibrational features of as-synthesized P3HT–ZnO:Ho3+ and P3HT–ZnO:Tm3+ thin films were investigated using Gaussian analysis. Relative to P3HT–ZnO:Tm3+ film, detailed Gaussian analysis of the fluorescence spectra revealed ...Read more
