摘要: Ruthenium (Ru)-II complexes such as the Ruthenium-tris(4,7-diphenyl-1,10-phenanthroline)dichloride (Ru(dpp)32+) is commonly used for dissolved oxygen sensing because of their profound advantages visible absorption, a large Stokes’ shift, good fluorescence quantum yields, long excitation lifetimes and quenching efficiency. In this study, we report on absorption characteristics when it exposed to where was determined using ultraviolet-visible (UV-Vis) absorbance spectroscopy. The results show that by decreasing concentration ofRu(ddp)32+, remained constant at optical wavelength 455nm while intensity changes with presence oxygen. sensitivity detecting proven improve increasing amount Ru(ddp)32+ used.
