Successive Ionic Layer Adsorption and Reaction Deposition and Optical Study of Ag2[Fe(CN)5NO] Thin Films Deposed on Glass Substrate

The elaboration of Silver-Iron(II) nitrosyl cyanide thin films have been performed on a glass substrate, using successive ionic layer adsorption and reaction (SILAR) method; the deposition experiments have been realized at room temperature using precursors solution of 10(-2) M with 120 dipping cycles. The as-deposed SilverIron( II) nitrosyl cyanide thin films were characterized using a various analytical technique such as: infrared spectroscopy, optical microscope, scanning electronic microscope, and X-ray diffraction. This study indicates that the as-deposited thin films have a polycrystalline structure with a grain size of more than 1 mu m. The optical study using UV-Vis spectrometry indicates that the as-obtained thin films Silver-Iron(II) nitrosyl cyanide have a large absorbance bonds on 209, 257, 350, and 500 nm corresponding to the fundamental electronic transitions (n. -> pi*, pi -> pi *, d -> pi*, and d -> d), along with an optical band gap's energy of 3.1 eV.
