Development of light-emitting electrochemical cells for novel applications

The work intended to make progress towards the objective of fiber-shaped light-emitting electrochemical cells (LECs). LECs comprising a film of poly(3,4-ethylenedioxythiophene): poly (styrenesulphonate) (PEDOT:PSS) cast from aqueous dispersion as the sole transparent anode were produced and characte...

Implications of using different cathode metals and varying the order of deposition of the films were studied and shown to have significant influence on device performance. Lastly, a novel fiber-like LEC in a coaxial geometry was produced, which promises bright prospects for new applications due to the flexibility of the used materials.
