CH3NH3Br solution as a novel platform for the selective fluorescence detection of Pb2+ ions.


ABSTRACT: The development of a simple fluorescent sensor for detecting the Pb2+ heavy metal is fundamentally important. The CH3NH3PbBr3 perovskite material exhibits excellent photoluminescence properties that are related to Pb2+. Based on the effects of Pb2+ on the luminescent properties of CH3NH3PbBr3, we design a novel platform for the selective fluorescence detection of Pb2+ ions. Herein, we use a CH3NH3Br solution at a high concentration as the fluorescent probe. Incorporation of PbBr2 into the CH3NH3Br solution results in a rapid chemical reaction to form CH3NH3PbBr3. Hence, the nonfluorescent CH3NH3Br material displays a sensitive and selective luminescent response to Pb2+ under UV light illumination. Moreover, the reaction between CH3NH3Br and PbBr2 could transform Pb2+ into CH3NH3PbBr3, and therefore, CH3NH3Br may also be used to extract Pb2+ from liquid waste in recycling applications.
