SURFACE MORPHOLOGY OF FE(III)-PORPHYRIN THIN LAYERS AS CHARACTERIZED BY ATOMIC FORCE MICROSCOPY
ABSTRACT: Surface morphology
of Fe(III)–porphyrin thin layers was studied using atomic force microscopy. The
thin layer samples used in these experiments were deposited by spin coating
methods on indium–tin-oxide substrates at room temperature under atmospheric
conditions. Variations of thin layer of Fe(III)-porphyrin were done by
modifying the rotational speed and the concentration of the solution. The
experimental results demonstrated that the Fe(III)–porphyrin layers were
observed as discrete nanomolecular islands. Both the number of nano-islands and
thickness of the layer increased significantly with increasing concentration. A
layer thickness of 15 nm was obtained for low concentrations of 0.00153 M and
become 25 nm for dense concentrations of 0.153 M. Conversely, the higher number
of islands were deposited on the surface of the substrate at a lower rotational
speed.
