Abstract
The impact of doping pure beta lead oxide (β-PbO) nanoparticles, produced by co-precipitation methods, with nickel (Ni) and lithium (Li) on their optical and structural characteristics. Li doping causes lattice expansion and decreases dislocation density, while Ni doping causes lattice contraction and increases dislocation density, according to structural analysis. Ni doping enhanced and Li doping attenuated the photoluminescence in the 450-550 nm region, according to optical investigations, which showed small changes in band gap energy but considerable fluctuations in photoluminescence intensity. Scanning electron microscopy (SEM) was used to better clarify the morphological effects of the dopants. This study offers significant perspectives on modifying the characteristics of β-PbO nanoparticles for prospective uses in environmental sensing, optoelectronics, and catalysis. Future directions include for creating prototype devices, investigating various synthesis techniques, and working with business to commercialize the results.
