利用柔性压印光刻技术在玻璃基板上制备了镀金纳米穹顶阵列。光学传输测量显示，复杂的等离子体共振被证明对阵列尺寸、金层的厚度和周围介质的折射率高度敏感。作为这些结构的一个有前途的应用，评估了纳米圆顶阵列的折射率传感能力。
Arrays of gold-coated nanodomes were fabricated on glass substrates using a soft nanoimprint lithography technique. Optical transmission measurements revealed complex plasmonic resonances that proved highly sensitive to the array dimensions, the thickness of the gold layer, and the refractive index of the surrounding medium. As one promising application for these structures, the refractive index sensing capabilities of the nanodome arrays were assessed.
