Different concentrations of Mg-doped ZnO nanoparticles (NPs) were synthesized by coprecipitation technique at 60°C. XRD data are used to study phase purity and crystal structure in different doping concentrations. The results indicated that increasing the doping from 0~7.5 wt.% caused a subsequent increase in FWHM in XRD and an associated systematic shift towards higher wavelength in the optical properties. Finally, the sensing of UV light is tested by observing the response of nanoparticles by exposing them to UV light and measuring the resistance in presence and absence of UV light.

“…As for photocurrent, thicker film means better light absorption efficiency, which improves the photo response [36]. Another reason is that thicker film produces larger grain size and therefore higher carrier mobility [37]. However, higher mobility causes dark current to be higher as well.…”

This paper reports a novel ultraviolet (UV) photodetector based on a TiO 2 /graphene hybrid, with high responsivity (0.482 A W −1 ) at 3 V bias and 330 nm irradiation, which is ~100 times higher than that based on pure TiO 2 . The collaboration of TiO 2 and graphene in the hybrid material contributes to the high performance of the device. To be more specific, graphene provides a large surface area to load sufficient TiO 2 nanoparticles, and the generated electrons are instantly collected due to the prominent electrical properties of graphene which can overcome the low quantum efficiency of pristine TiO 2 caused by recombination of photoinduced electron-hole pairs. The device was fabricated on a flexible substrate using a facile spraying method that shows the possibility of broadening the future of photodetectors in wearable devices. An on-board interface circuit based on commercial IC components is implemented to collaborate with the photodetector to demonstrate a UV sensing application.
