We have developed MoS2nanosheets and CdMoS4hierarchical nanostructures based on a UV light photodetector. The surface morphologies of the as-prepared samples were investigatedviafield emission scanning electron microscopy (FESEM) and transmission electron microscopy (TEM). The performance parameters for the present photodetectors are investigated under the illumination of UV light having a wavelength of ∼385 nm. Upon the illumination of UV light, the CdMoS4-based photodetector device showed a better response to UV light compared to the MoS2device in terms of photoresponsivity, response time (∼72 s) and recovery time (∼94 s). Our results reveal that CdMoS4hierarchical nanostructures are practical for enhancing the device performance.
