摘要:

以聚苯乙烯微球的单层和双层胶体晶体为模板, 通过模板电沉积银, 移除模板后得到单层和双层银通孔阵列, 并用作基于增强光透射(EOT)的等离子传感器. 结果表明, 与单层银通孔阵列相比, 双层通孔阵列的传感灵敏度和品质因子都有很大提升, 最高分别达到559.71 nm/RIU(RIU: Refractive index unit)和14.28 RIU-1.

Abstract:

One- and two-tier Ag through-void arrays for extraordinary optical transmission(EOT)-based plasmonic sensing were fabricated by electrodeposition of Ag through monolayer and bilayer colloidal crystal template of polystyrene spheres, followed by removal of the template. Experimental results reveal that compared with one-tier Ag through-void arrays, two-tier Ag through-void arrays show largely improved sensitivity and figure of merit(FOM), which reach 559.71 nm/RIU(RIU: Refractive index unit) and 14.28 RIU-1, respectively. These suggests a low cost, feasible way for the fabrication of high quality EOT-based plasmonic sensor using routine techniques in which the tools used are accessible to most researchers.

Key words: Surface plasmon, Through-void array, Template electrodeposition, Self-assembly, Refractive index sensor
