High electroluminescence of the ZnS:Mn nanoparticle/cyanoethyl-resin polymer/single-walled carbon nanotube composite using the tandem structureElectronic supplementary information (ESI) available. See DOI: 10.1039/c2jm33131d

The EL performance of the tandem structured phosphor/polymer/SWCNT composite was greatly increased by structural and material effects, which led to increased tunneling charge carriers into phosphor, resulting in improved luminance. The tandem structured composite EL device exhibited a 1570% increase in the luminance compared to the raw phosphor EL device. We proposed a new type of tandem-structured electroluminescence device using the ZnS:Mn phosphor/polymer/carbon nanotube composite. High luminance and efficiency were successfully achieved.
