Using these bare core/shell QDs as the active layer in the studied device gave no EL at all. However, yellow EL with the maximum brightness of 56834 cd/m2, maximum current efficiency of 4.7 cd/A and maximum power efficiency of 2.3 lm/W is obtained from the device structure of indium tin oxide/poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate)/ADS233YE:0.4 wt.% CIS/ZnS QD/Ca/Al those of which correspond to approximately 4 and 2 folds of enhancements in the brightness and luminous and power efficiency values, respectively, compared to that of the device without CIS/ZnS. © 2015 Elsevier B.V.en10.1016/j.tsf.2015.05.006info:eu-repo/semantics/closedAccessCadmium freeCopper indium sulfideHybrid polymer light emitting diodePolyfluoreneSingle layerYellow emissionZinc sulfideArticle589153160Q2
