Methylamine Gas Sensor Based on Fluorescent Perovskite Nanocrystal Nanofibers Incorporating Aggregation-Induced Emission Materials
Source abstract
Abstract
This study introduces a methylamine gas sensor based on a composite material of halide metal perovskite (MAPbBr 3 ) and the aggregation-induced emission (AIE) material (S)-OBN-tCz. Using electrospinning technology, superhydrophobic MAPbBr 3 &(S)-OBN-tCz@PMMA nanofibers were fabricated to enhance the specific surface area and stability of the sensing unit. The sensor exhibits high selectivity toward methylamine gas, enabling precise detection across a broad concentration range and demonstrating excellent repeatability. Additionally, the incorporation of AIE material has successfully improved the signal intensity of optical sensors through Förster resonance energy transfer mechanism and passivation effect, thereby effectively enhancing the sensitivity of sensors.
