In this work, we demonstrate nano‐structured silver particles photo‐reduced from silver nitride (AgNO 3 ) solution using visible‐light‐activated titanium dioxide (TiO 2 ), which can be a convenient and effective substrate for surface enhanced Raman spectroscopy (SERS) observation. Visible‐light‐activated carbon‐containing TiO 2 nanoparticles are applied to photo‐reduce and form nano‐structured silver from AgNO 3 upon visible‐light illumination. Photo‐reduced nano‐structured silver is used as an active substrate for SERS studies of TiO 2 as well as nano diamond and TiO 2 . The photo reduction of AgNO 3 and SERS observation can be obtained by simultaneously using the same visible laser excitation. The coexistence of the anatase phase with small admixture of the rutile phase in the TiO 2 can be observed using SERS. The carbon structure in the carbon‐containing TiO 2 was determined to be sp 2 type carbon bonding by SERS. Copyright © 2009 John Wiley & Sons, Ltd.
