Attempt has been made to synthesize hexagonal Cd1-xZnxS (x=0-0.75) by a simple solution phase method. The samples were characterized by XRD, SEM and UV-Vis spectroscopy. The XRD studies confirmed the formation of hexagonal modification of the above mentioned ternary system. SEM revealed formation of an agglomerated product with grain sizes of similar to 100 nm. The mode of growth was confirmed as Ostwald ripening from UV-Vis studies. Shift in the exciton peak on increasing the Zn2+ was explained on the basis of formation of the solid solution. Photoluminescence studies reveal a shift in the luminescence band with Zn signifying the formation of solid solution. Also the band arises from the surface states demonstrating high concentration of surface defect states. (C) 2007 Elsevier B.V. All rights reserved.
