Highly dispersed Ag nanoparticles embedded in alumina nanobelts as excellent surface-enhanced Raman scattering substrates

Nearly monodispersed Ag nanoparticles embedded in alumina nanobelts were fabricated with a template method by integrating facile coordination polymerization with an atomic layer deposition (ALD) technique. The composite nanobelts with specific hierarchical micro/nano-structure showed superior SERS properties for the R6G probe molecule.
