Quantum Dots: Ultrafast Solar-Blind Ultraviolet Detection by Inorganic Perovskite CsPbX3 Quantum Dots Radial Junction Architecture (Adv. Mater. 23/2017)

Ultrafast solar-blind UV detection, enabled by a hybrid inorganic perovskite CsPbX₃ quantum-dot radial junction architecture, achieves rise/fall response times of 0.48/1.03 ms and a high responsivity of 54 mA W⁻¹ at 200 nm without an external power supply, as described by Linwei Yu, Xiangxing Xu, and co-workers in article number 1700400. These results pave the way toward large-area manufacturing of high-performance Sibased perovskite UV detectors in a low-cost procedure.
