An Influence of Concentration of Polyvinylpyrrolidone on the Morphology of Silver Metal Formed from AgNO3 Aqueous Solution

الملخص EN

Metal silver rods having a partly regular direction on the substrate are synthesized from the fine copper particles on acrylic plastic plate immersed in 50 μM-PVP and 0.1 M-AgNO3 aqueous solution.

An increase of PVP concentration in the AgNO3 aqueous solution inhibits the growth of the string-shaped silver and dendrite-shaped silver as well as polyol method.

The absorbance of the plasmon peak around 410 nm immersed in 0.1 M-AgNO3 aqueous solution at 25∘C for 24 hours increased with an increase of the PVP concentration.
