英文摘要 | In this work, all-solution processed, multi-layer yellow quantum dot light emitting diodes (qleds), consisting of a hole transport layer of poly(9-vinylcarbazole), emissive layer of cuins2/zns (zcis) qds, and electron transport layer of zno nanoparticles, are fabricated. to improve the carrier-balance in qleds, a ligand-exchange strategy is employed to replace n-dodecanethiol that caps the surface of cuins2/zns quantum dots with 2-ethylhexanethiol. after this processing, improvement of current efficiency and external quantum efficiency of qleds is achieved. the optimized diodes exhibit a maximum luminance of 2354 cd m(-2) and an external quantum efficiency of 0.63%, together with a lower turn-on voltage (decreases from 3.1 v to 2.7 v) using these ligand-exchanged qds as emitting materials. furthermore, cuins2-based qleds in our study exhibit color retainability with increasing voltage and prolonged use, and show great promise for practical application. |
