dc.description.abstractWe report on light-emitting devices based on a green-phosphor compound (Mn-doped zinc silicate, Zn2SiO4: Mn) dispersed in a conductive polymeric blend (poly-o-methoxyaniline/polyvinylene fluoride, POMA/PVDF-TrFE). The devices exhibited high luminance in the green, good stability and homogeneous brilliance over effective areas up to 5 cm(2). The electroluminescence (EL) spectrum presented essentially the same characteristics as the photoluminescence (PL) and cathodoluminescence spectra, indicating that the light emission originates from decay of the same excited species, regardless of the excitation source. Operating characteristics were analyzed with current density - voltage (J - V) and luminance voltage ( L - V) curves to investigate the nature of the electroluminescence of the active material, which is still not completely understood.
