Perovskites have attracted substantial attention on account of their excellent physical properties and simple preparation process. Here we demonstrated an improved photodetector based on solution-processing organic-inorganic hybrid perovskite CH3NH3PbI3-xClx layer decorated with CsPbBr3 perovskite quantum dots. The CH3NH3PbI3-xClx-CsPbBr3 photodetector was operated in a visible light region, which appeared high responsivity (R = 0.39 A/W), detectivity (D* = 5.43 x 10(9) Jones), carrier mobility (mu(p) = 172 cm(2) V-1 s(-1) and mu(n) = 216 cm(2) V-1 s(-1)), and fast response (rise time 121 mu s and fall time 107 mu s). The CH3NH3PbI3-xClx-CsPbBr3 heterostructure is anticipated to find comprehensive applications in future high-performance photoelectronic devices.
