Low-temperature synthesis and characterization of cadmium sulfide nanowires grown using simple chemical reaction through the pores in an alumina template

The synthesis of cadmium sulfide (CdS) nanowires using a simple chemical reaction (ion exchange) method through the pores in an alumina template is reported. The chemical reaction takes place inside the pores and the reaction yield is deposited in the pores. The morphological, structural and optical characterization of CdS nanowires is also reported. The Raman spectrum shows that CdS nanowries have good crystalline nature. The value of the optical bandgap observed is 2.7 eV for CdS nanowires. Room temperature photoluminescence measurements exhibit an emission peak at about 507 nm.
