本文报道了一种低成本、高相容性的液相一步合成法，用于合成高纯度CsPbBr 3微/纳米片单晶。在高纯度CsPbBr 3的基础上，我们进一步制备了一种能够平衡光电探测的低维光电探测器，它既具有高的外量子效率，又具有快速的时间响应，这在以前报道的低维光电探测器中几乎没有实现。
Here, we reported a low-cost and high-compatibility one-step liquid-phase synthesis method for synthesizing high-purity CsPbBr3micro-/nanoflake single crystals. On the basis of the high-purity CsPbBr3, we further prepared a low-dimensional photodetector capable of balanced photodetection, involving both high external quantum efficiency and rapid temporal response, which is barely realized in previously reported low-dimensional photodetectors.
