Mössbauer study of C18N/Fe Langmuir-Blodgett layers

Research output: Contribution to journalArticle

Abstract

Langmuir-Blodgett (LB) films of octadecanoyl hydroxamic acid (C18N) complexed with Fe 3+ ions have been prepared at various subphase pH values. The LB films consisting of different number of layers were investigated by 57Fe conversion electron Mössbauer spectroscopy (CEM) at room temperature. The CEM detector contained a piece of α-iron, enriched with 57Fe, using as an internal standard. The Mössbauer pattern of the C18N/Fe LB films is a doublet with parameters δ = 0.35 mm/s and Δ = 0. 74 mm/s. A gradual increase of the relative occurrence of the doublet compared to the sextet of the internal standard was observed with the increasing number of layers, indicating the nearly uniform distribution of Fe among the LB layers.
