Abstract
In present work, MoS2 nanosheets were produced through a hydrothermal technique using urea surfactant for humidity sensing applications. Also, Cobalt doping was done to study the effects on crystallography, morphology, optical properties and humidity sensing properties of MoS2. X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM) were used to study crystal structure and morphological analysis. Functional groups were examine through FTIR spectra and Optical properties was observed using UV–Visible. XRD data confirms the hexagonal phase of MoS2 and from SEM images flower-like spheres to wrapped nanosheet structures were observed. Optical band gap was estimated for all samples using UV–Visible data. The comparative analysis of pristine and cobalt-doped MoS2 was discussed here. Also, the humidity sensing behaviour of both pristine and cobalt-doped MoS2 was studied in this paper.
