Resumo
Double layers and mixed single layers of two electronically complementary columnar liquid crystals show
enhanced performances in light emitting diodes compared to devices made from single layers of only one
of the materials. A shift from green to red electro luminescence is observed between single-material and
two-material devices, assigned as resulting from triplet exciplexes in the electroluminescence of the two-
material films, where as singlet exciplex states contribute to the photoluminescence of the mixture and
double layer films.
