摘要

Much effort has gone into research on light-emitting electrochemical cells (LECs) in recent years. LECs have a simple structure and can be fabricated using low-cost methods and materials and are seen as the next big thing in organic devices after organic light-emitting diodes (OLEDs). In particular, expectations are high, in that LECs could be used to create a new generation of low-cost lighting systems, making use of their surface-emitting property. Getting such systems to the market will require the development of highly efficient white light-emitting LECs. A variety of methods for obtaining white emission based on the light-mixing principle have been explored. Among these, the use of exciplexes formed between donor-type and acceptor-type molecules is one of the more promising. Exciplex emission is broad in spectrum and can be used to produce LECs with a high color rendering index. In this progress report, the recent developments in research into LECs designed to utilize exciplex emission and present technologies used to obtain white emission are discussed. The potential for using thermally activated delayed fluorescence to improve efficiency is described. Finally, the latest developments in optical engineering techniques for LECs are also discussed.
