Abstract:
In this work, self-assembly of radial nanostructured ZnO homojunction were synthesized by a kind of two-step method. A supplementary growth mechanism is used to explain the formation of nanostructured ZnO homojunction. Photoluminescence (PL) spectra reveals that the ultraviolet (UV) emission peak of In doped ZnO has an obvious blue-shift compare to that of final junction nanostructures.PL spectra also show that the intensity of the green emission obviously decreases after ZnO layer coating, which means that the ratio of intensity of UV emission to that of green emission increases. It may ascribe to the capping treatment compensating the defects at the surface of In doped ZnO, and suppressing the defect luminescence of ZnO nanostructures.
