In this work, 0-dimensional (0D) CsPbBr3 QDs were integrated with 2D bismuthene having ultrafast carrier mobility, to obtain a 0D/2D nanohybrid. Moreover, an excellent charge transfer efficiency (0.53) and an appreciable quenching constant of 2.3 × 105 M-1 were observed. Tuning the ratio of bismuthene in the Bi/perovskite nanohybrid achieved the quantified control of charge transfer efficiency and quenching performance at the interface.
在这项工作中，将具有超快载流子迁移率的二维二碲化铋与零维（0D）CsPbBr3 QDs 集成，得到 0D/2D 纳米杂化材料。此外，观察到了优异的电荷转移效率（0.53）和可衡量的猝灭常数 2.3×105 M-1。通过调整 Bi/钙钛矿纳米杂化材料中二维二碲化铋的比例，实现了对界面处电荷转移效率和猝灭性能的量化控制。
