The paper reports tailoring of the optical bandgap in SILAR deposited Cd x Zn 1-x S alloy
films. Acetates and chlorides of zinc and cadmium were used to obtain the films. Two
separate routes were employed to achieve desired alloy composition in the films. In the first
route, the molar concentration of the precursors was varied. In the second route; various
volumes of precursors (with fixed concentration) were used. The films were polycrystalline
with predominant hexagonal phase. The bandgap of the films varied from 2.4 eV to 3.5 eV …
