The Concentration-Dependent Distribution of Tris(4,7'-diphenyl-1,10'-phenanthroline) Ruthenium (II) within Sol-Gel-Derived Thin Films

Abstract

Organic dye-doped glasses, viz., ruthenium (II) tris(4,7'-diphenyl-1,10'-phenanthroline) [Ru(dpp)

Effect of catalyst on the fluorescence quenching of [Tris (4, 7-diphenyl-1, 10-phenanthroline) ruthenium (II) dichloride] for dissolved oxygen detection

“…In this paper, we report on the dissolved oxygen (DO) application. Several materials were reported to be used in DO sensor, for example [Ru(dpp) 3 ] 2+ , [Ru(bpy) 3 ] 2+ ,and Ru[(Phen) 3 ]Cl 2 [9][10][11][12]. For our work, we have chosen [Ru(dpp) 3 ] 2+ as the sensing material because it has good photostability, high luminescence quantum yield, long lifetimes and good quenching efficiencies.…”

“…Thus, it suitable to be applied for DO sensing application due to the oxygen measurement needs the flurophore that show high photostability, high fluorescence quantum yield and long lifetime. Over the past decade, [Ru(dpp) 3 ] 2+ luminescence based sensor also have been used for medical, process control, and industry application [10] [13]. Although there are many reports on the preparation of the [Ru(dpp) 3 ] 2+ , not many reported on the effect of the catalyst on the fluorescence behavior.…”
