基于胶体刻蚀的微纳锥孔结构及其在智能显色方面的应用

Surface plasmon resonance (SPR) has been widely used in many fields and attracted increasing interest. With lots of excellent researches, various micro- and nano-structures were fabricated to promote this technology. Based on the modified colloidal lithography with advantages of flexibility, simple operation, low cost and the potential ability of fabricating three-dimensional (3D) structures, 3D nanohole structure, hollow cone structure and 3D cone-hole structure with the property of SPR would be prepared to improve transmission properties, nature of the chromogenic, transferability and response to the external environment, etc. Through researching in the mechanism, properties characterization and simulation of the micro- and nano-structure, the relation between the structure and model would be established, and finally realize the unity of theoretical modeling and experimental model to guide the experiment. Based on the theoretical model and experiment, micro- and nano-structures, such as the multiple composite cone-hole arrays, strong responding SERS substrate with single component or multiple composite structure, would be further developed, which provides the theoretical and experimental basis for applications of SPR in optical micro-apparatus, physical, chemical and biological sensors and smart coloring.
