  • Description: In this work, the supramolecules (riboflavin and melamine) were used as a template for the self-assemble of ZnO nanostructures by adding into the growth solutions. After that, the composite nanostructures of nanoflowers-like p-type NiO/n-type ZnO nanosheets were grown following a two-step on the fluorine doped tin oxide substrate by the hydrothermal method. The riboflavin and melamine have a role in UV emission. Taking these advantages into account, the current–voltage (I–V) characterization of the ZnO/NiO heterojunction was performed at room temperature and showed an obvious nonlinear and rectifying response. Strong UV absorption with fast switching was observed from the ZnO/NiO composite heterojunction. The proposed UV photodetector based on this nanocomposite is more stable, possesses fast rising and decaying time response of approximately 100 ms. Further, a low leakage current was observed for the presented device. The findings in the present study indicates that the controlled...
