Magnetic-Field-Dependent Effect on the Synthesis of Cu2O Crystals
The effect of magnetic field on the morphology and properties of Cu2O has been investigated by using a high magnetic field (B = 7 T) during the synthesis of Cu2O. Transmission electron microscopy (TEM) images showed that the variation of Cu2O crystal microstructures from nanospheres to nanoparticle-aggregates under the introduction of external magnetic field. And the optical band gap energy (Eg) of Cu2O was changed from 2.51 eV (nanospheres) to 2.27 eV (nanoparticle-aggregates). The effect of high magnetic field on the structure and properties is expected to be widely used to improve various crystals.
