Abstract
Electrochemiluminescence (ECL) is a phenomenon in which light is emitted from the excited state of a redox-active material generated by electrochemical reactions. ECL devices have various advantages in terms of structure and simple fabrication, and they are therefore expected as next generation emitting devices. In this paper, we report that electrochemically triggered upconverted luminescence through triplet–triplet energy transfer (TTET) and subsequent triplet–triplet annihilation upconversion (TTA-UC) is first observed in the electrochemiluminescence properties of a Ru complex/diphenylantracene (DPA) containing electrochemical device. Further, ultra-fast quick response in emission is observed in DNA modified electrode cell.
