The present work describes the synthesis of Cd0.9Zn0.1S and Cd0.87Zn0.1Ni0.03S by chemical co-precipitation method. The XRD profile proved the cubic crystal structure of the samples without any impurity related phases. The reduced size from 63 to 51 Å has been discussed by Ni addition in Cd0.87Zn0.1Ni0.03S structure. The noticed anomalous optical studies and the elevated transmittance at Ni doped sample suggested them for the fabrication of efficient opto-electronic devices. The energy gap reduction during the substitution of Ni = 3% is explained by the generation of extra energy levels associated with defects within the two bands.
