The thin films of zinc sulphide (ZnS) with nanograins are produced on (glass) substrates at 250°C using the spray-pyrolysis deposition technique (SPDT). The films have a polycrystalline cubic structure with preferred orientation along (111) direction of growth. The optical characteristics of the thin ZnS film indicate a direct optical energy gap of 3.320 eV. The film displays a thickness of 250.25 nm with grain sizes ranging from 9.76 nm to 11.46 nm. For approximate values, the measurements are done with the use of a computer simulation tool 'Hebal Optic'. It is also observed for all the films that there is an inverse proportional change in resistance to temperature and that the formed films have two activation energies.

KEY WORDS: software 'Hebal Optic', nano-ZnS, thiourea, energy gap, spray-pyrolysis deposition technique
