Submicroporous CdS films were fabricated by a two-step replication process, in which porous anodic alumina was used as a template. The films were grown on a porous gold support of the same structure, resulting in a free-standing CdS/Au membrane. The diameter of the holes of the regular porous structure is in the order of 100 nm. Moreover, the replicated CdS film consists of small-sized quantized crystalline particles, the size of which are in the range of 5 nm. Thus, the film is ordered in the 5 and 100 nm domain forming a superstructure.
