利用纳米球刻蚀法制备了二维六角密排三角形银纳米阵列,通过加入铬过渡层并改变其位置和改变金属沉积角度,研究它们对点阵结构的影响.实验发现,加入铬过渡层所形成的银纳米点阵结构较无铬层有很大改善,三角形角部更加尖锐,更能满足传感器对信号检测的要求.同时,该过渡层应蒸镀在模板球排列之后,才能获取更大面积的二维银纳米点阵结构.在沉积角度对制备二维银纳米点阵的影响的实验中,基片没有旋转,采用垂直镀膜方式更容易得到结构完整、结合较牢固、且面积较大、角部尖锐的二维银纳米点阵.吸收光谱测量进一步验证了铬过渡层对二维银纳米点阵形貌结构的改善作用.这些为下一步的生物修饰以及生物化学传感器的制备提供了先决条件.
Two-dimensional hexagonal close-packed triangular silver nano-arrays were prepared by nanosphere etching, and their influence on the lattice structure was studied by adding chromium transition layer and changing its position and changing the metal deposition angle. It was found that by adding chromium transition layer The formation of silver nano-lattice structure than chromium-free layer has greatly improved triangle corners more sharp, more able to meet the sensor signal detection requirements.At the same time, the transition layer should be deposited in the template ball arrangement, in order to obtain greater Area of the two-dimensional silver nano-dot matrix structure in the deposition angle of the preparation of two-dimensional silver nano-dot matrix experiment, the substrate is not rotated, the vertical coating easier to get the structure is complete, combined with a solid and larger area , Sharp corner of the two-dimensional silver nano-lattice. Absorption spectroscopy measurements further validated the chromium transition layer on the two-dimensional silver nano-lattice morphology and structure of the role of these for the next step of biological modification and biochemical sensor preparation provided prerequisites.
