| 제목 | Highly Luminescent Red-Emitting In(Zn)P Quantum Dots Using Zinc Oxo cluster: Synthesis and Application to Light-Emitting Diodes |
| 초록 | Despite the importance of separatingnucleation steps from growth steps for the production of monodisperse highlyluminescent In(Zn)P quantum dots (QDs), the practical implementation of thisstrategy is hindered by the high reactivity and fast depletion of conventionalP precursors. This problem can be mitigated through the use of (i) Zn oxoclusters, which effectively regulate the kinetics of QD growth and prevent thefast depletion of conventional P precursors in the nucleation step, or (ii)seed-mediated continuous growth methods, which avoid secondary nucleation inthe growth step and yield red-emitting InP QDs. Herein, we successfully synthesizered-emitting In(Zn)P QDs with a high photoluminescence quantum yield (>93%)and a low emission bandwidth (full width at half maximum = 38 nm). The preparedIn(Zn)P QDs are used to fabricate QD light-emitting diodes with a maximumbrightness of 1164 cd m−2 and an external quantum efficiency of 3.61%. |
