Abstract

ZnO thin films were deposited on glass substrates by radio-frequency (RF) reactive sputtering under different O2 flow rates, with constant Ar flow rate (50sccm). The dependence of O2 flow rate on s...

Abstract

Interesting tunable physical chemical properties of silver nanoparticles under metal nanoparticle family can have great impact in modern technologies specially concerned with biological applications. The systematic investigation on synthesis of silver nanoparticles is performed by tuning the concentration of HH, AgNO3, and PVP. The structural and morphological analysis were characterized using XRD, FE-SEM, and TEM. The formation of stable silver nanoparticle differentiated with tunable textured colors of highly crystalline (fcc) quality are remarked with particle size 10–15 nm. The antibacterial activities against E. coli and S. aureus conferred well for the concentration of 6 mM HH:3 mM AgNO3:3 mM PVP.
