M. Ahmad et al., Sensing material for oxygen gas prepared by doping sol-gel film with tris (2,2-bipyridyl)dichlororuthenium complex, J NON-CRYST, 290(1), 2001, pp. 86-91
A ruthenium complex, tris (2,2-bipyridyl)dichlororuthenium (TBDR) has been
entrapped inside sol-gel films for the purpose of O-2 sensing based on fluo
rescence quenching. The properties of this sensing material including fluor
escence spectral, repeatability, reproducibility and the response curve are
described. Results obtained from this study show that TBDR immobilised in
thin films prepared via the sol-gel process gives a reversible response tow
ards O-2 gas and the sensing material is regenerable by using N-2 gas. (C)
