Structural, Morphological, Optical and PL Studies of Neodymium Doped ZnS Glass Plate by Nebulizer Spray Pyrolysis Method

Herein we have present the preparation of Nd doped ZnS thin films on glass substrate by simple nebulizer spray pyrolysis (NSP) method at 450 0 C. XRD, SEM, and UV-Vis Spectrometer were used to analyze the Structural, morphological, and optical behavior of the prepared samples. Nature of polycrystalline hexagonal structure with no secondary phases was confirmed by X-ray analysis. Extra particle creation on the surface of the Nd doped thin film was observed in high magnified SEM images. Room temperature PL studies depicts that the luminance behavior of the parent sample was enormously changed during the Nd element interstitial with ZnS lattice. Optical band gap value varies from 3.51 eV to 3.58 eV for 3% Nd doped ZnS film ascribed the increasing of film thickness and diminishing of film transparencies.
