Gold and Silver Nanoparticles Synthesis and Applications

In the present study, PbSe nanostructures have been synthesized by using [bis(salicylate)lead(II)]; [Pb(Hsal)2] as lead precursor in the presence of sonochemical method in aqueous solution. Besides, the effects of reaction time, ultrasonic power, and surfactant on the morphology and particle size of products were studied by SEM images. It was found out that the size and morphology of the products were greatly influenced by these parameters. The XRD studies indicated the production of pure cubic PbSe nanostructures could only happen in the presence of ultrasonic radiation. The average diameter of the PbSe nanostructures was 12 nm. Products were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), photoluminescence (PL) and EDX analysis.
