An Influence of Concentration of Polyvinylpyrrolidone onthe Morphology of Silver Metal Formed from AgNO3Aqueous Solution

[摘要] 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-AgNO3aqueous solution. An increase of PVP concentration in the AgNO3aqueous 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-AgNO3aqueous solution at 25∘C for 24 hours increased with an increase of the PVP concentration.
