Abstract

Ruthenium (Ru)-II complexes such as the Ruthenium-tris(4,7-diphenyl-1,10-phenanthroline) dichloride (Ru(dpp)3 2+) is commonly used for dissolved oxygen sensing because of their profound advantages such as visible absorption, a large Stokes' shift, good fluorescence quantum yields, long excitation lifetimes and good oxygen quenching efficiency. In this study, we report on the absorption characteristics of (Ru(dpp)3 2+) when it is exposed to dissolved oxygen where the absorption was determined using ultraviolet-visible (UV-Vis) absorbance spectroscopy. The results show that by decreasing the concentration of Ru(ddp)3 2+, the absorbance remained constant at optical wavelength of 455nm while the intensity changes with the presence of dissolved oxygen. The sensitivity of detecting dissolved oxygen was proven to improve by increasing the amount of Ru(ddp)3 2+ used.
