“…In line with the Raman analysis, XRD results also reveal that the crystalline structures of ZnS for the ZnO/ZnS core shell structure 14,15 with the seed layer electrodeposition time of 5 s had stronger both c-axis growth (002) 22 ZnO crystalline structures 23,24 and (111) 25 ZnS cubic structures than all the other samples as shown in Fig. 5.…”

In this research, ZnO/ZnS core/shell nanostructures were grown by electro-hydrothermal methods on titanium substrates. To optimize the growth of the nanostructures, the ZnO seed layer electro-deposition time was adjusted to modify the surface of the nanostructure. Multiple material characterizations were performed to examine the surface morphologies and material properties of the nanostructures. Results indicate that ZnO/ZnS nanostructures with ZnO deposition time of 5 sec had well-grown ZnO nanorods and high-quality ZnS nanoparticles for ZnO/ZnS core shell structures. ZnO/ZnS nanostructures on titanium substrates show promising for future development of titanium substrate-based biomedical and optoelectronic devices in the future.

“…The rGO in the ZnO seed could enhance the growth of ZnO NRs in the c-plane and inhibit the lateral growth. The ZnO structure has two polar planes, namely, (002) and (00-2), and a charged surface that could cause a faster growth rate along the (002) direction; additionally, rGO enhances the reaction with OH and a Znterminated c-plane [15]. The results of the material analyses indicate that the diameter of ZnO NRs can be effectively modulated by adjusting the rGO compositions, which may have the potential to optimize the ZnO NRs according to the device performance.…”

“…Wang et al [12] reported that seed layer and precursor concentration can change the morphology of ZnO NRs. Recently, some researchers have made efforts to control ZnO nanostructures by putting different elements such as polyethyleneimine molecules, surfactants, and graphene-related materials into growth solutions or into the seed layer [13][14][15].

It is essential to control the size of zinc oxide (ZnO) nanorods (NRs) for the improvement of tunable optoelectronic applications. In this paper, we present the results of a systematic and extensive study that explored the effect of growth parameters on the morphology and optoelectronic properties of ZnO NRs. We found that the length and width of ZnO NRs can be efficiently tuned by carefully controlling the growth parameters and by modulating the ZnO seed with reduced graphene (rGO). These results could give us a better understanding of the growth behavior of ZnO NRs and could contribute to the control of the morphology of these NRs for nano-device applications. Moreover, the effect of growth parameters on the optoelectronic properties of ZnO NRs was thoroughly investigated by fabricating light-emitting diodes (LEDs) with different morphologies of the ZnO NRs and the correlation between the morphology and the luminescence efficiency of ZnO was established. These investigations illustrate a viable and highly promising approach to enhance the luminescence intensity of ZnO NR-based LEDs by 500 times. The present work will guide researchers in the production of low-temperature, size-controlled, and aligned ZnO NRs for tunable highly luminescent optoelectronic applications.
