摘要：
Chunk shaped ZnO nanostructures (CSNS) simultaneously doped with Li and Mn for varying Li/Mn concentrations have been synthesized using wet-chemical method. Their crystal structural, optical and magnetic properties at room temperature (RT) were then investigated, which revealed that all the samples have a single phase with the wurtzite structure. Undoped and co-doped ZnO chunk-shape structures has been demonstrated by transmission electron microscope (TEM). The Mn/Li incorporation also creates more lattice defects and disorders, which influence directly characteristic photoluminescence (PL), FTIR and UV-vis spectra of Zn1-x-yMnyLixO CSNS. Where green emission due to concentration of defects is seen. Magnetic measurements by VSM and the ferro fluid of synthesized nano ZnO by Faraday optical rotation for various concentration of Mn and Li in nano ZnO are done. Change of magnetic and magneto-optic (MO) properties due to Mn and Li ions are discussed in detail. (C) 2014 Elsevier B.V. All rights reserved.
