Abstract:

The organic-inorganic hybrid materials produced from tetraethoxysilane, citric acid and ethylene glycol and immobilizing complex tris(4,7-diphenyl-1,10-phenanthroline) ruthenium(II) dichloride (Rudpp) are prepared and their morphology is studied by atomic force microscopy. The studied hybrid matrix is suitable for production of thermally stable, dense and uniform films with a good adhesion to glass. The matrix ensures uniform distribution of the immobilized dye.
Films prepared by dip coating at a withdrawn speed of 0.4 mm s-1 from sonicated sol with molar ratio TEOS : CA : EG = 4 : 1 : 1 produced by acid catalyzed hydrolysis were studied by multifractal analysis.
The structural complexity of the 3D surface roughness revealed that the 3D surface can be described using the multifractal geometry. The generalized dimension Dq and the singularity spectrum f(I±) provided quantitative values that characterize the local scale properties of the 3D surface geometry at nanometer scale.
Detailed surface characterization of the surface topography was obtained using statistical parameters, according with ISO 25178-2: 2012.
