Photoelectrochemical etching and energy gap control of silver clusters

Abstract

An energy gap of Ag clusters is controlled on the basis of photoinduced electron transfer from the clusters to TiO2. With 2.6 eV light irradiation, Ag32 clusters on TiO2 are oxidized and disappear. With <1.6 eV light, the energy gap of Ag32 is changed from ∼1.4 to ∼1.7 eV because of photoetching.
