Spray pyrolysis was used to create nanocrystalline cadmium sulphide thin films on glass substrates in this study. Researcher looked examined how substrate temperature 400 oC affected the thin films’ structural, morphological, optical, electrical, Photodetection Analysis, and NO2 gas sensor characteristics. Analyses of the thin films’ optical absorption, X-ray diffraction, and field emission scanning electron microscopy (FE-SEM) have been conducted. The thin films, according to the X-ray results, were polycrystalline and had a hexagonal phase crystallite. The thin films’ surface is homogenous, consistent, and crack-free.The grains typically have an average size of 37.86 nm. The optical band gap values that have been found fall within the 2.4 eV range.  Based on Hall effect testing, the thin films were found to have n-type conductivity. The generated CdS sheets were also used to create a photodetector, which worked admirably. A high photoresponsivity and external quantum efficiency were achieved using a 400 oC substrate temperature. At 40 ppm, the CdS film had a maximum reaction of 60% and was determined to be extremely sensitive to NO2.
