摘要
研究了铬过渡层对纳米球刻蚀法制备二维银纳米点阵结构的影响。首先利用自组装的方法在玻璃基底上制备出单层排列的聚苯乙烯纳米球阵列,然后使用物理气相沉积的方法在二维聚苯乙烯纳米球阵列上沉积一层铬层作过渡层和银层,最后将玻璃基底在乙醇溶液中超声移除聚苯乙烯纳米球,得到二维的银纳米点阵。实验发现,随着铬过渡层厚度的增加,制得的二维银纳米点阵阵列趋于完整,单个的银纳米颗粒由椭圆状转变为三角形形状。实验中测量了所得到的二维银纳米结构的吸收光谱。
Effect of Cr buffer layer on the structure of 2D Ag nanoarrays by nanosphere lithography was studied. Polystyrene nanosphere monolayer was deposited onto the glass substrate by the self-assembly technique. The Cr buffers with different thickness were deposited onto the template of the PS monolayer,and then a Ag film was deposited. At last, the polystyrene nanospheres were removed by the sonication in absolute ethanol solution,resulting in aligned Ag nanoarrys. It was found that the better-defined Ag solid triangle-like nanoarrays could be fabricated as the Cr buffer layer became thicker. The absorption spectrums of Ag nanoarrays were studied too.
