Applicability of liquid–liquid interface reaction technique for the preparation of zinc sulfide nano particulate thin films

Abstract Thin films of zinc sulfide are prepared by the liquid–liquid interface reaction technique. Cubic and hexagonal mixed phase is observed from electron diffraction (ED) of the film showing a spot pattern with faint rings in the background. The optical absorption edge shows a blue shift with respect to bulk indicating the nano nature of the film material. Transmission electron microscopy confirms the nanostructure of the film with particle size in the range 2–9 nm, with peak maxima between 3–5 nm consistent with the particle size suggested by optical absorption studies.
