Phosphorescence characteristics of ruthenium complex as an optical transducer for biosensors
The saturation intensity, photobleaching, and decay lifetime of tris(4,7-diphenyl- 1,10-phenanthroline) ruthenium(II) chloride [ Ru ( dpp ) 3 ] are investigated. The saturation point was estimated to be 11.8 W ∕ cm 2 and subsequently measured to be 11.5 W ∕ cm 2 . Photobleaching of this dye at a pea...
