Abstract

Indium tin oxide (In₂O₃-SnO₂-90/10 wt%, ITO) is a semiconductor material with excellent electrical conductivity. In this paper, ITO was deposited on a multimode optical fiber by magnetron sputtering technique and characterized by using Scanning Electron Microscopy (SEM). It is subsequently used as a working electrode in a three-electrode system to study its electrochemical behavior in different solutions. In 0.1 M KCl containing such redox probes as 1 mMofK₃[Fe(CN)₆] were discussed by Cyclic voltammetry (CV) method at different scan rates. The observed electrochemical processes are quasi-reversible and diffusion-controlled. The results of the investigation inject new vitality to enhance the intersection of electrochemistry and optics disciplines, and also lay the foundation for dual-domain determination.
