Abstract
In this study, cadmium oxide (CdO) nanoparticles were synthesized using laser produced plasma technology with varying energy levels (300, 400, 500, and 600) mJ. These nanoparticles were deposited as a thin layers on glass surfaces (at a rate of 100 pulses). They were examined structurally and optically using a Scanning Electron Microscope (FESEM), X-Ray spectrophotometer (XRD), Atomic Force Microscope (AFM), and UV-visible spectrophotometer. The energy gap of the films varied from (1.5 eV) to (2.1 eV). We note that the energy gap decreases with increasing laser intensity. The FESEM and AFM images show a large anisotropy in the structure as the roughness varies with different energies. X-ray investigations indicated the presence of many crystals and a variation in the crystal structure of the film. The Figure of Merit (F.O.M) diagram revealed that the optimal energy was (400 mJ). A gas sensor for gas (NH3) was created, and the impact of increasing gas ratios and temperature on gas sensitivity over time was investigated.
