Pr Norihisa Kobayashi works in the Group of Advanced Imaging and Systems (G-AIMS), from the Graduate School of Engineering in Chiba Univertisty (Japon). His work focuses on the development of electrochromic and/or electroflurochromic display devices, as well as blue electrochemiluminescent devices and plasmonic substrates whose colour is switched according to the size of the nanoparticles.

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 seminar, Pr Norihisa Kobayashi reports 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 achieved in DNA modified electrode cell.
