摘要：
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, Ag-32 clusters on TiO2 are oxidized and disappear. With <1.6 eV light, the energy gap of Ag-32 is changed from similar to 1.4 to similar to 1.7 eV because of photoetching.
