Highly efficient fluorescent and colorimetric sensing of organic amine vapors based on Organometal halide perovskite nanostructures

Abstract

Volatile organic amine vapors existed in various areas of human life which can cause a series of harmful effect on environment and human life. Thus, the detection of organic amine vapors with sensitivity and selectivity is of great needs. This work reported a simple, low-cost, selective and sensitive fluorescence detection of trace organic amines vapors based on CH3NH3PbBr3 (MAPbBr3) nanoplates (NPs) and nanowires (NWs). Upon exposure with organic amines vapors, the fluorescence of MAPbBr3 strikingly and quickly attenuated (<4S), and the color of MAPbBr3 changed from yellow to white for some of the organic amines (depend on the R group of R-NHX). This change was rooted in the crystal structure of MAPbBr3 change after contacted with different amines. We believe this result is not only a great advance for trace detection of organic amine vapors but also equally important for fundamental research of organometal halide perovskite.
