Optical properties of the novel ligand (5-ClCPAI) thin films Prepared by spray pyrolysis method

Abstract

This research consist of synthesized of heterocyclic compounds derivatives the novel from imidazole of the ligand: 2-[2-(5-Chloro carboxyl phenyl) azo]-imidazole and  the identification  of ligand (5-ClCPAI) were identification and analyzed by using Nuclear magnetic resonance (¹H-NMR), Mass spectrometry (MS), Ultraviolet visible (UV), Fourier transform infrared (FTIR), X-ray diffraction analysis (XRD) and Scanning electron microscopy-Energy dispersive X-Ray spectroscopy (SEM-EDS). Thin films of ligand prepared of concentration of (0.05, 0.1, 0.3)M membrane pure and doped of 10% hexaferrite (SrFe₁₂O₁₉) of concentration (0.05)M was prepared of thin films with thickness (1000 ±10)nm  the preparation of membranes by method spray pyrolysis. The study of optical properties of thin films pure and doped study spectral of absorbance and transmittance within the wavelength (200-800)nm the results shows of the transmittance decrease of the molar concentration increase and doped and the absorbance arise with the increase in molar concentration and doped and energy bandgap decline with arise in molar concentration and doping, the study of structure properties of the Thin films prepared through (XRD) where the results show membranes multiple crystallization and preferred trend of growth is (101) particle.
