| Abstract: | ![]()
CdS nanoclusters of four different sizes were integrated with ruthenium‐complex dyes. The cluster–dye crystalline composites, [Cd4(SPh)10][Ru(bpy)3], [Cd8S(SPh)16][Ru(bpy)3], [Cd8S(SPh)13?Cl?(CH3OCS2)2][Ru(phen)3], [Cd17S4(SPh)28][Ru(bpy)3], and [Cd32S14(SPh)40][Ru(phen)3]2 (phen=1,10‐phenanthroline and bpy=bipyridine), show intense absorption in the visible‐light region. They also exhibit size‐dependent photocurrent responses under the illumination of visible light. The photocurrent increases with increased cluster size. The dyes also have significant influence on the photocurrent generation of the composite. |
