Spin coating of ZnS nanostructures on filter paper and their characterization

•We explored a low cost method of synthesis of Cu doped nanostructures on flexible substrates.•Conducting interlinked nanofiber resembles original fiber morphology provokes the new field of template synthesis.•Improved optical and structural properties makes them suitable for various flexible optoelectronic applications.

In this paper we have reported spin coating of Cu doped Zinc sulphide nanostructures on filter paper flexible substrates. Zinc chloride and thiourea were used as precursors of zinc and sulphur. The samples were characterized by XRD, FE-SEM, EDAX and UV–visible spectrum studies. All the diffractogram peaks confirm the cubic structure of ZnS with small peak of Cu indicates incorporation of Cu into ZnS lattice. FE-SEM micrographs exhibit fibrous morphologies of ZnS structures on filter paper. Compound structures on flexible substrates show ohmic behavior with conductivity about 3.07×106 (Ωcm)−1 to 4.27×106 (Ωcm)−1. Excellent photoluminescence property doped with copper makes them suitable for flexible opto-electronic devices.
