Abstract
Electrochemically-generated chemiluminescence (ECL) is a light-emission process achieved through a series of electrochemical processes on luminophore dissolved in electrolyte (including electric double layer formation, oxidation/reduction at the electrodes, transport of luminophores, charge transfer between oxidized/reduced luminophores, and radiative relaxation). Unlike previous light-emitting devices employing solid-state emissive layer, devices based on ECL (referred to as ECLD) are constructed using a liquid or gel state emissive layer, allowing for novel light-emitting device platform with simple fabrication and enhanced form factor. In this talk, basic working principle of ECL (in comparison with conventional OLEDs or LECs) will be explained, particularly with the focus of the transport properties of luminophores within the electrolyte. Methods to improve the luminance and operation stability of ECLDs in terms of the operation condition and device structures will be introduced. Finally, a new ECL pathway will be introduced exploiting an oxidative annihilate partner molecule to enhance ECL intensity of the luminophore based on Marcus-landscape engineering of the charge transfer process. This new pathway is referred to as the facilitated mixed-annihilation ECL. We anticipate this talk will provide insight into further developing the new class of a light-emitting device platform.
