Directionally electrodeposited gold nanoparticles into honeycomb macropores and their surface-enhanced Raman scattering

The ordered honeycomb films of dioctadecyldimethylammonium (DODMA(+))-encapsulated sandwich-type [(Mn(H(2)O)(3))(2)(WO(2))(2)(BiW(9)O(33))(2)](10-) ({Mn(2)Bi(2)W(20)}(10-)) are used as templates to directionally electrodeposit gold nanoparticles into their macropores. Consequently, the prepared hierarchical Au-filled films present a strong surface-enhanced Raman scattering of rhodamine 6G molecules.
