To use SERS in routine, on-line studies for analytical purposes, the substrates should be stable, reproducibly prepared, inexpensive, and easy to make. We report in this symposium that optically tunable, SERS-active Ag films can be reproducibly fabricated on dielectric substrates by the thermal decomposition of silver carboxylate. The nanostructured Ag films prepared in this way are expected to provide a new type of substrate materials for developing SERS as an ultrasensitive analytical tool.展开更多
