Light-Emitting Electrochemical Cells: The Design and Realization of Flexible, Long-Lived Light-Emitting Electrochemical Cells (Adv. Funct. Mater. 16/2009)
A highly functional flexible light-emitting electrochemical cell during operation is depicted in this cover image. By optimizing the composition of the active material and by employing an appropriate operation protocol, as described by Fang et al. on page 2671, more than one month of uninterrupted operation at significant brightness (>100 cd−2 ) and relatively high power conversion efficiency (2 lm W−1 for orange-red emission) is realized.
