Optical, structural and photoluminescence properties of PbS nanoparticle synthesized by plasma-induced chemical reaction technique in aqueous solution

This study aims to prepare and investigate how the exploding current and the concentration of sodium sulfate impact the structural optical photoluminescence and particles size characteristics of PbS nanoparticles. An explosive wire system was utilized during experimentation where different currents (50, 60 and 70) A were passed through a lead wire with a diameter of 0.5 mm. Three concentrations of Sodium sulfate salt (5, 7.5 and 10) mg/cm³ where prepared by dissolved, 1, 0.7.5 and 0.5 gm from Sodium sulfate in100 mal water to produce sulfur ions that react with lead ions when the wire explodes, resulting in the formation of PbS nanoparticles. The particles' structure was examined by X ray diffraction showing a face centered cube stretcher (fcc). Based on this, we may infer the feasibility of producing lead sulfate nanoparticles using a simple, cost-effective, high-purity, and ecologically sustainable method. Optical properties show that as the current increases, the energy gap increases, which means that the current affects the energy gap.
