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 mu M-PVP and 0.1 M-AgNO(3) aqueous solution. An increase of PVP concentration in the AgNO(3) 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-AgNO(3) aqueous solution at 25 degrees C for 24 hours increased with an increase of the PVP concentration.
