)ruthenium(Ⅱ) (Ru-Dppz) was prepared by the sol-gel method. The fluorescent behaviors of the complex in ethanol and xerogel were investigated. As a result
the emission band of the composite material attributed to the transition from the metal-to-ligand charge transfer (MLCT) shows blue shift compared with that in ethanol. The lifetime of the complex in xerogel was increased compared with that of the pure solid complex. The sensing material with Ru-Dppz as indicator demonstrated good Stern-Volmer plot
high sensitivity
fast response time and long-term stability. The sensitivity was improved using an organically modified silicate (ormosil) as a matrix.
