To research the properties of hybrid quantum dot light emitting diodes (QLEDs),QLEDs that exhibit orange light were fabricated in this paper using red and green hybrid quantum do t with a proportion of 1∶1as the light emitting layer,the structure of the hybrid quantum dot light emitting dio des is ITO/PEDOT:PSS/ poly-TPD/QDs (red and green quantum dot mixed with a proportion of 1∶1)/ZnO/Al .Red QLEDs with the structure of ITO/PEDOT:PSS/poly-TPD/QDs (red light)/ZnO/Al were also fabricated as a con trast sample.Experiment results show that the orange QLED has a lower current density as well as a lower luminan ce compared with the red QLED fabricated.However,the current efficiency of the orange QLED is much higher th an that of the red QLED.The study found that the energy level and the thickness of every functional layer ar e essential in improving the performance of the device.It is the best that the energy level of the luminesce nt material is able to capture both hole and electron so that the carrier could be trapped in the light emitting lay er,thus improves the current efficiency.Besides that,optimizing the thickness of each functional layer is a lso a key factor in improving the performance of the device.
