SILAR Deposition of Ni(bpy)(3)X: {X = (NCS)(2), (Fe(CN)(5)NO), and (Ag(CN)(2))(2)} Thin Films on Glass Substrates

摘要

The authors focused on the preparation of thin layers based on hybrid materials (organometallic complexes) deposited onto glass substrates. The deposition experiments of [Ni(bpy)(3)](NCS)(2), [Ni(bpy)(3)](Ag(CN)(2))(2), and [Ni(bpy)(3)](Fe(CN)(5)NO) were performed on glass slides (18mm x 18 mm) by successive ionic layer adsorption and reaction (SILAR) method. The influence of some parameters, such as dipping cycle numbers (30, 60, and 120 dipping cycles), temperature (20 degrees C, 30 degrees C, 40 degrees C, and 50 degrees C), precursors concentration (10(-3), 10(-2), and 10(-1) M), and the nature of the counteranions (NCS-, [Fe(CN)(5)NO](-2), [Ag(CN)(2)](-)) were studied. Different methods (UV-Vis, SEM, FTIR, and XRD) were used to characterize the deposited layers to determine the absorption coefficient () and gap energy (E-g) of the materials.
