Lead sulfide nanoparticles (PbS) are utilized in various applications across multiple fields. A set of PbS nanocomposites was prepared on glass substrates at room temperature and under a pressure of 2.5 × 10-2 mbar using pulsed laser deposition (PLD). The laser energy used ranged between 300 mJ and 600 mJ, with a wavelength of 1064 nm and 100 pulses. The structural properties of the prepared PbS nanoparticles were analyzed using X-ray diffraction (XRD) at different laser energies (300, 400, and 500 mJ). The results confirmed the well-ordered structure of the PbS nanoparticles. The analysis showed that the composition of the metal nanoparticles was polycrystalline, with lead sulfide exhibiting the best orientation. It was observed that all films had a polycrystalline, cubic structure. The surface topography of the films was studied using an atomic force microscope (AFM). As the concentration of PbS nanoparticles increased, the inhibition effect decreased, providing insights into the surface morphology. The results indicated that the average grain size was 86.49 nm at 500 mJ laser energy, with further detailed results presented in the tables of the paper.
