In this research, X-ray diffraction of the powder (PVP polymer, Eosin B dye, and silver nitrate) and (EB/PVP, AgNO3/PVP, EB/AgNO3/PVP) films have been studied. Casting method is used to prepare homogeneous films on plastic petri dishes. All parameters accounted for the X-ray diffraction; full width half maximum (FWHM), Miller indices (hkl), size of crystalline (D), Specific Surface Area (S) and Dislocation Density (δ).The nature of the structural of materials and films will be investigated. The XRD pattern of PVP polymer was amorphous structure with two broader peaks and the Eosin B dye and silver nitrate have crystalline structure. While the mixture between these materials led to appearing some crystalline peaks into XRD pattern of PVP polymer.
