In this study, we have synthesized the molybdenum sulfide quantum dots (MoS2 QDs) and zinc sulfide quantum dots (ZnS QDs) and demonstrated a highly efficient green phosphorescent organic light-emitting diode (OLED) with hybrid poly (3,4-ethylenedioxythiophene)/poly (styrenesulfonate) (PEDOT:PSS)/QDs hole injection layer (HIL). The electroluminescent properties of PEDOT:PSS and hybrid HIL based devices were explored. An optimized OLED based on the PEDOT:PSS/MoS2 QDs HIL exhibited maximum current efficiency (CE) of 72.7 cd A−1, which shows a 28.2% enhancement as compared to counterpart with single PEDOT:PSS HIL. The higher device performance of OLED with hybrid HIL can be attributed to the enhanced hole injection capacity and balanced charge carrier transportation in the OLED devices. The above analysis illustrates an alternative way to fabricate the high efficiency OLEDs with sulfide quantum dots as a HIL.

Different Thickness

Organic light emitting diode is a Solid state lighting devices, the charge transporters must be infused from the anode and cathode yet the execution, lifetime, effectiveness and solidness of these devices are normally administered by the correct thickness of the material layers and terminal/organic interfaces at the anode contacts. In this paper we exhibit a new approach using different thickness of organic material of emissive layer and hole injection layer in OLED. We could enhance the effectiveness of doping materials by framing exciplex improved OLED devices and concentrate their execution enhancement by utilizing different thickness. In this work different thickness of emission layer, ETL layer and HIL is taken and maximum luminous efficiency of different devices were observed
