Consideration of Cadmium-doping Effect on Crystal Lattice Properties of Tin Oxide (IV) Nanofibers

This research focuses on the effect of cadmium doping on the crystal lattice of the tin oxide (IV) nanofibrous layer. This nanofibrous layer was prepared using the electrospinning method which had no beads and had a circular cross-section. The effects of cadmium doping of these nanofibers on the crystal lattice were studied using X-ray diffraction patterns. The values of tin oxide (IV) lattice parameters and in turn, the unit cells volume and its density increased very little. This change can be related to the entry of cadmium into the crystal structure of tin oxide (IV). However, doping with cadmium had no effect on unit cell angles and the same tetragonal structure was preserved. It should be noted that the peaks shifted slightly toward larger angles which were attributed to the formation of voids at the location of anions (oxygen).
