Postsynthesis Phase Transformation for CsPbBr 3 /Rb 4 PbBr 6 Core/Shell Nanocrystals with Exceptional Photostability.
ACS Applied Materials & Interfaces 2018 July 12
Lead halide perovskite nanocrystals (NCs) as promising optoelectronic materials are intensively researched. However, instability is one of the biggest challenges needed to overcome before fulfill their practical applications. To improve their stability, we present a postsynthetic controlled phase transformation of CsPbBr3 toward CsPbBr3 /Rb4 PbBr6 core/shell structure triggered by rubidium oleate treatment. The resulting core/shell NCs show exceptional photostability both in solution and on-chip. The solution of CsPbBr3 /Rb4 PbBr6 NCs can remain over 90% of the initial emission photoluminescence quantum yields after 42 h of intense light-emitting diodes illumination (450 nm, 175 mW/cm2 ), which is even better than the conventional CdSe/CdS quantum dots whose emission drop to 50% after 18 h under the same condition. We believe that the exceptional photostability should be resulted from the protection of the robust Rb4 PbBr6 shell on CsPbBr3 NCs.
