Abstract
Silver nano-rod, nano-zigzag, nano-saw, and nano-particle arrays are fabricated with glancing angle bideposition. The structure-dependent anisotropic optical properties of those bideposited nanostructured arrays are measured and investigated. The equivalent birefringence values of nano-rod and nano-zigzag arrays are much larger than crystals found in nature and liquid crystal used in display products. The fact that induced localized plasmon-magnetic field between nanorods dominates the strong phase retardation between p-polarized and s-polarized transmitted wave. For the nano-saw, the strong localized electric field induced between the saw teeth leads to strong SERS signals. Although the bideposited nanoparticles own weak morphological anisotropy, strong optical phase retardation is still detected at wavelengths near 400 nm.
Highlights
Silver nano-rod, nano-zigzag, nano-saw, and nano-particle arrays are fabricated with glancing angle bideposition
The high s-polarized extinction of the nanosaw array (NSA) occurs at wavelengths around 400 nm because the transverse plasmonic mode of a silver rod is excited near the plasmon resonant wavelength
The birefringence of the silver-air composite is very sensitive to the aspect ratio of its nano-structures according to the effective medium approximation
Summary
Silver nano-rod, nano-zigzag, nano-saw, and nano-particle arrays are fabricated with glancing angle bideposition. In this work, glancing angle deposition (GLAD) is used to bideposit serially silver nanozigzag arrays with different pitch lengths.
