Abstract:
The phenomenon of electroluminescence (EL) induced by the passage of ion current has been observed for the first time in polymeric cation- and anion-exchange membranes of the MK-40K and MA-41K types, respectively, occurring in an equilibrium sodium sulfate solution. With respect to the measured light flux, the EL is classified as low-intensity emission. Estimation of the temporal characteristics of this emission showed evidence for a recombination mechanism of the observed phenomenon.
