Structural, optical, and magnetic studies of iodine-doped CdO nanopowders and films
Source abstract
Abstract
Iodine-doped CdO powders of different iodine contents have been synthesized by thermal dissociation of Cd complex. In addition, I-doped CdO thin films have been grown on glass substrates by a physical vapor deposition method. The effects of iodine doping on the structural, magnetic, and optical properties of the host CdO powder and film were systematically studied. The X-ray diffraction study shows that the incorporated I−-ions most likely occupy oxygen vacancies (VO) created naturally in CdO lattice as point defects during synthesis. Thus, I-doping increases the unit-cell volume of host CdO, causes bandgap narrowing, and removing the weak d0 ferromagnetic (FM) component of CdO. Therefore, the weak FM component of undoped (d0) CdO is defect-induced phenomenon or induced by the created oxygen vacancies (VO). In the present fundamental investigation, real experimental connection between active VO, I-doping, and magnetic properties of I-doped CdO was observed and discussed.
