Abstract
In this study, the structural, thermal, optical, electrical and magnetic properties of Zn(1-x)MgxO (x = 0.0, 0.1, 0.3, 0.5) nano-compounds obtained by the addition of MgO to pure ZnO nano-compounds obtained by solid state reaction were investigated in detail. These nanomaterials were deposited by spin coating technique in heterostructure of ZnO/Zn(1-x)MgxO. It was found by detailed structure solution that the crystal systems of nanomaterials obtained with MgO additive remained hexagonal, but the space group was transferred from P63mc to P6/mmm. The thermal gravimetry analysis shows the stability of prepared nanomaterials, the UV–Vis spectroscopy shows that the bandgap of the prepared was decreased from 3.02 to 2.52 eV with the Mg doping percentage. The Magnetization measurements at room temperature showed that all four of these Zn(1-x)MgxO nanostructures exhibited soft ferromagnetic behavior. The analysis of the ZnO/Zn(1-x)MgxO heterostructure showed that its band gap was increased from 3.69 to 3.79 eV, its carrier density was decreased from 1.14×1019 to 4.20×1013 cm−3 which introduce it as a good material to be used in optoelectronic devices field.
