    摘要:

    改進(jìn)Brust法,我們合成了1-己硫醇修飾的原子組成為Ag0.66Au0.33的合金納米顆粒。以該合金納米顆粒為構(gòu)建單元我們采用溶液法成功組裝了波導(dǎo)耦合一維合金光子晶體結(jié)構(gòu)。利用該結(jié)構(gòu)搭建的生物傳感器的靈敏度是相同條件下純金結(jié)構(gòu)的2.5倍。金-銀合金納米顆粒組裝的波導(dǎo)耦合金屬光子晶體傳感器以其低成本的制備工藝和簡單的測試光路表現(xiàn)出潛在的應(yīng)用前景。

    Abstract:

    By improving Brust method, we synthesize 1-hexanthiol modified gold-silver alloy nanoparticles with an atomic composition of Ag0.66Au0.33. By using the alloy nanoparticles as “building block”, we successfully assemble one-dimensional waveguided alloy photonic crystals through a solution processible method. Under the same conditions, the sensitivity of the biosensor built with the waveguided alloy photonic crystals is 2.5 times that of the similar structure made of pure gold. Gold-silver alloy nanoparticles assembled waveguided metallic photonic crystals exhibits potential application in biosensors due to its low-cost fabrication process and simple testing methods.
