This paper highlights the photoresponsivity property of a hybrid-ZnO nanowire (ZnO NW) photodetector to a white LED source with a wavelength range of 400–700 nm. The use of methanol via the vapor phase transport method was utilized to achieve the incorporation of carbon and oxygen particles with Zn to form hybrid-ZnO NWs. Field emission scanning electron microscope, X-ray diffraction, and Raman scattering techniques were used in the identification of morphology, polycrystalline structure, and ${D}$ -, ${G}$ -, and 2-D bands, respectively. Positive photoresponsivity and negative photoresponsivity of the hybrid-ZnO NWs were studied with the LED distances 1–4 cm from the hybrid-ZnO NWs for varied bias voltage from 1 to 4 V. A reproducible photoresponsivity with response times ranging from 182 to $345~\mu \text{s}$ was measured using an oscilloscope. The proposed technique demonstrates the great potential possessed by hybrid-ZnO NWs in optoelectronic applications in the near future.
