Abstract: (1657 Views)
Zn2SnO4 has attracted attention for fabrication of transparent electronic devices such as solar cells. In this paper, Zn2SnO4 nanopowders with different values of Mn were synthesized by means of solid-state reaction method. The structural investigation revealed that the prepared powders at below 4% impurity had a single phase structure. At higher concentration of Mn, besides the Zn2SnO4 phase, secondary phases formed, namely Mn2O3 and Mn3O4. In the second step, the effect of vacuum annealing on the ferromagnetic properties of the prepared single-phase Mn-doped Zn2SnO4 was investigated. The optical characterization revealed that the band gap of the vacuum-annealed samples was higher than 4 eV. Furthermore, the formation of diluted magnetic semiconductor by doping Mn in Zn2SnO4 was verified.
