Abstract

This work presents a novel light-modulated gas sensor based on hybrid Indium Selenide (InSe)-graphene synthesized via the liquid phase exfoliation (LPE) technique. We investigated the effects of the operating temperature and light irradiation on the sensing layer performance. The morphology, composition and structural characteristics of the sensing layer are analyzed using different material characterization techniques including scanning and transmission electron microscopies, X-ray photoelectron spectroscopy, and Raman. The response to NO 2 of the InSe-graphene hybrid gas sensor while operated under dark conditions or excited at one of three different wavelengths (i.e., 375, 470, and 530 nm), which correspond to UV, blue and green light, respectively, is studied. Results show that UV light excitation of the film when operated either at room temperature or at 150 degrees C resulted in an enhanced NO2 response, with a limit of detection below 50 ppb, and an excellent selectivity against other gaseous like CO, CO2, C6H6 and H2. Remarkably, the hybrid nanomaterial is characterized by showing significantly faster response and recovery times than those often found in the literature.
