Using a unique glancing angle co‐deposition technique, face‐centered cubic Ag nanoparticles have been embedded into aligned polycrystalline MgF 2 nanorods with different topological shapes, such as tilted, zigzag, vertical, and helical nanorods. The optical properties of the artificial nanocomposite materials, such as surface plasmon resonance and polarization absorbance, are determined by the size of the Ag nanoparticles as well as the alignment and shape of the MgF 2 nanorod arrays. The combination of co‐deposition and glancing angle deposition provides a unique way to design novel nanocomposite materials and doped nanorod arrays.
