Obaid_2022, title={Synthesis and Characterization of Silver Nanoparticles Generated by Cold Plasma}, url={http://thedesignengineering.com/index.php/DE/article/view/9108}, abstractNote={<p>In this paper, silver nanoparticles (AgNPs) were synthesized using an atmospheric pressure non-thermal plasma method at different exposure time. XRD and Field emission scanning electron microscopy (FESEM) were used to investigate the structural and morphology properties of the silver nanoparticle. While optical properties were investigated using UV/VIS spectroscopy. The synthesized AgNPs appeared surface Plasmon resonance (SPR) centered at (398,402,400,390,395) nm. For all samples, the X-ray diffraction pattern revealed that the strong intensity peaks indicated crystalline nature and a face-centered cubic structure of silver nanoparticles. The AgNPs had an average crystallite size of 30.9 nm. Moreover, (FE-SEM) confirm the formation of Ag structure with particle sizes ranging (17−55) nm with spherical shapes. Results show that the plasma exposure time plays a crucial role in modifying the silver nanoparticles properties such as surface area, grain size, and optical stability.</p&gt;}, number={1}, journal={Design Engineering}, author={Hamsa A.
