Optical properties of Silver-Iron(II)nitrosyl cyanide thin films deposed on glass micro-slides using SILAR method

摘要

This study is focused on the elaboration of Silver-lron(II) nitrosyl cyanide thin films, using successive ionic layer adsorption and reaction (SILAR) method; the deposition has been performed on glass substrate after 120 dipping cycles using precursors solution of 10(-2) mol.L-1 at room temperature. The elaborate Ag-2[Fe(CN)(5)NO] thin films have been characterized using infrared spectroscopy, optical microscope, scanning electron microscope, and XRD. The optical study using UV-Vis spectrometry indicates that the obtained thin films has a large absorbance bonds on 209, 257, 350, and 500 nm corresponding to the fundamental electronic transitions between the highest occupied molecular orbital (HOMO) and the lowest unoccupied molecular orbital (LUMO), with an optical band gap energy of 3.1 eV.
