Colour tuning and enhancement of gel-based electrochemiluminescence devices utilising Ru() and Ir() complexes

Combining luminophores in ratios that compensate for energy transfer provides a readily selectable range of new emission colours for gel-based electrochemiluminescence devices (ECLDs).

Description
Summary:Combining luminophores in ratios that compensate for energy transfer provides a readily selectable range of new emission colours for gel-based electrochemiluminescence devices (ECLDs). A novel blue ECLD luminophore is also introduced and shown to enhance the intensity of the conventional green emitter through a mixed annihilation ECL mechanism. Peak-to-peak voltages were minimised using asymmetric potential pulse sequences, which increased the longevity of the ECLD emission. Combining luminophores in ratios that compensate for energy transfer provides a range of new emission colours for gel-based electrochemiluminescence devices.
