Abstract
This paper focuses on Cu3BiS3 nanocomposites that were produced using solvothermal technique in the presence of a capping agent known as Mercaptoacetic acid (MMA). The study also shows that these nanostructures have the possibility of being used in optoelectronic and gas sensing industries. FE-SEM analysis, XRD diffraction pattern, and UV-Vis spectroscopy reveal regular nanostructures with crystalline nature and the ability to control their optical features. Electrical measurements show promising PIV performance and temperature-dependent Hall Effect measurements provide information about main charge transport channels. The study of the dynamic response of the nanocomposite to NO2 is performed through dynamic response curves as a function of operating temperature and shows a more detailed and richer interdependence between operating temperature and sensing performance. Interestingly, the sensitivity is maximized at 100°C which is a remarkable improvement in the development of the room-temperature gas detecting device. This work expands the knowledge on ternary chalcogenide nanocomposites and suggests ways in which they can be implemented in future optoelectronic and environmental applications. This systematic study helps in understanding the structural, optical, electrical and gas sensing characteristics of Cu3BiS3 nanocomposites for various technological applications.
