dc.description.abstract 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 composition analysis were investigated in detail. Both pure and Yb(sup3+) doped ZnO were found to have hexagonal wurtzite structure with the particle size in the range of 4–7 nm in diameter. Addition of Yb(sup3+) ions into the ZnO host lattice led to enhanced exciton emission from ZnO indicating energy transfer from Yb(sup3+) ions to ZnO or a reduction of oxygen related defects. en_US
