Highly luminescent Copper doped CdS nanorods were prepared by modified sol-gel method. The sol was prepared by continuous stirring of mixture of ethylene glycol, ethanol and acetic acid with Cadmium chloride (CdCl2) and thiourea as the precursors of Cd and S respectively at 50 °C temperature for 3 h. For Cu doping cuprous chloride was added slowly. Fine green and blue colored particles were obtained. The samples were analyzed by XRD, SEM, optical transmission and photoluminescence studies. Broad peak of (101) is observed in X-ray diffractograms for undoped CdS. Intensity of this peak increases with increase in copper (Cu) doping. In SEM, large number of islands is observed in undoped CdS. On doping with copper these islands grow as more and more particles bind together. Undoped structures are generally spherical with uniform size and start to reassemble in ordered rodlike structure on increase in doping.
