Abstract

Abstract Luminescent lead halide perovskite nanocrystals (LHP NCs) have attracted great attention. This work reports the synthesis of well‐defined core/shell structured CH3NH3PbBr3/β‐cyclodextrin (MAPbBr3/β‐CD) nanodots via host‐guest interaction between β‐cyclodextrin and hexylamine. The MAPbBr3/β‐CD nanodots show high luminescence with photoluminescence quantum yields (PLQYs) of 89.7% in solution and 38.0% in solid state. The MAPbBr3/β‐CD nanodots have superior stability in water, under heat and UV light exposure due to the formation of a β‐CD shell, which gives them great potential for optoelectrical and biological applications.
