Abstract
In this investigation, a clad-modified fiber optic sensor is reported for NO2 gas detection. CdS is coated over cladding-removed region by Chemical Bath Deposition (CBD) which acts as the gas-sensing medium. CdS is coated over four fibers each with a different coating duration of 10, 20, 30 and 40 min. Characterisation of CdS is done by Scanning Electron Microscope (SEM), Energy-dispersive x-ray spectroscopy (EDX), x-ray Diffraction (XRD), Photoluminescence study (PL) and UV-visible absorption spectroscopy. The spectral response for different concentrations of NO2 is studied on the four fibers separately, and it is analysed.
