Cd-Zn sulphide films synthesized via chemical bath deposition technique.
Nanocrystalline phase of Cd-Zn sulphide films were seen in XRD studies.
Nanocrystalline structures of the films were also confirmed by the SEM.
The band gap of these films is a combination of composition and size.
EU and σ studies ascribed the shrinkage of absorption edges around the optical band-gaps.
