Enhanced exciton emission from ZnO nano-phosphor induced by Yb3+ ions

Author: Kabongo, GL ; Mhlongo, Gugu H ; Mothudi, BM ; Hillie, KT ; Swart, HC ; Dhlamini, MS Date: 2014 In 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
Time-resolved fluorescence decay and Gaussian analysis of P3HT-derived Ho3+- and Tm3+-doped ZnO nanostructures

Author: Kabongo, GL ; Mbule, PS ; Mhlongo, Gugu H ; Mothudi, BM ; Dhlamini, MS Date: Jan 2020 The 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
