Abstract: A new kind of organically modified sol-gel (ormosil) as a matrix for oxygen-sensitive sensor, in which dimethyldime-thoxysilane was selected as an organic modifier in the precursor is described. The fluorescent behaviors of different ruthenium complexes in solution and ormosil film were studied. The sensing film with different kind ruthenium complex as an indicator developed in this paper was characterized in terms of efficiently quenched by oxygen. A new ormosil provides a more desirable environment for oxygen response through increasing film hydrophobicity by the content of the nonbridging Si-CH3 groups has been discussed. The sensing film with tris-(4,7-diphenyl-1, 10-phenanthroline) ruthenium(II) as an indicator is selected because of its characteristic with high quenching efficiency, fast response time, high luminescence intensity and long-term stability.
