The synthesis and applications of nanomaterials have gained vast attention during the last two decades. Among these nanomateri-als both ZnO and CuO have been studied and utilized to fabricate many nanodevices for different applications. The potential applica-tions cover many important areas such as sensing, electronics and photonics. This thesis describes the fundamental properties of these two nanomaterials, the low temperature synthesis of ZnO na-norods, CuO nanostructures, and CuO/ZnO composite nanostruc-tures. The realization of potential devices based on ZnO, CuO and their composites for lighting and sensing applications is also intro-duced. Specifically, efforts have been made to fabricate white light emitting diodes by combining ZnO nanorods with different poly-mers. Furthermore, the optimization of the fabricated light emit-ting diodes is investigated. Finally, by using the low temperature synthesis of CuO/ZnO nanocorals and we have further exploited them to realize high sensitivity humidity sensor.
