چکیده
Light-emitting diodes based on quantum dots as an active emission can be considered a promising next generation for application in displays and lighting. We report theoretical investigation of green at 550 nm microcavity inorganic–organic light-emitting devices Zn (Te, Se) alloy layer. Distributed Bragg Reflector (DBR) has been applied bottom mirror. The realization high-quality DBR consisting both high low refractive index structures is investigated. layers are (ZrO2, SiNx, ZnS), while those (Zr, SiO2, CaF2). ZnS/CaF2 three pairs with step (Δn = 0.95) revealed broad stop bandwidth (178 nm) achieved reflectivity 0.914.

Top-emitting quantum dots light-emitting devices employing microcontact printing with electricfield-independent emission
Recent breakthroughs in quantum dot light-emitting devices (QD-LEDs) show their promise in the development of next-generation displays. However, the QD-LED with conventional ITO-based bottom emission structure is difficult to realize the high aperture ratio, electricfield-independent emission and flexible full-color displays. Hence, we demonstrate top-emitting QD-LEDs with dry microcontact prin...

We investigate the mechanism of operation of hybrid organic/colloidal quantum dot light emitting devices QD-LEDs . Novel quantum dot QD deposition methods allow us to change the location of an emissive QD monolayer within a QD-LED multilayer structure. We find that the quantum efficiency of devices improves by 50% upon imbedding QD monolayers into the hole transporting layer 10 nm away from the...
متن کاملNiO as an inorganic hole-transporting layer in quantum-dot light-emitting devices.
We demonstrate a hybrid inorganic/organic light-emitting device composed of a CdSe/ZnS core/shell semiconductor quantum-dot emissive layer sandwiched between p-type NiO and tris-(8-hydroxyquinoline) aluminum (Alq3), as hole and electron transporting layers, respectively. A maximum external electroluminescence quantum efficiency of 0.18% is achieved by tuning the resistivity of the NiO layer to ...
