Abstract
Methylammonium lead bromide, i.e., MAPbBr3, has been synthesized at room temperature through chemical stirring method. The structural characterization of synthesized MAPbBr3 has been confirmed through X-ray diffraction technique, Field emission scanning electron microscopy, Fourier transform infrared, thermogravimetric analysis and UV-Vis spectroscopy. Afterward, the optical properties (excitation wavelength 415 nm; emission wavelength = 535 nm) of MAPbBr3 were confirmed through a photoluminescence spectrophotometer. To end, MAPbBr3 has been used for the optical detection of nitroaromatic compounds, i.e., nitrobenzene (NB), dinitrobenzene (DNB), dinitrotoluene (DNT), trinitrophenol (TNT) in hexane. Our research has confirmed the 7.1 ppb and 10 ppb detection limit (LOD) for nitrobenzene and di-nitrobenzene only using MAPbBr3, respectively. Importantly, we found out the selectivity %, i.e., 1.3% and 2.7% in the case of nitrobenzene and dinitrobenzene sensing using MAPbBr3 in hexane, respectively.
期刊介绍:
Journal of Chemical Sciences is a monthly journal published by the Indian Academy of Sciences. It formed part of the original Proceedings of the Indian Academy of Sciences – Part A, started by the Nobel Laureate Prof C V Raman in 1934, that was split in 1978 into three separate journals. It was renamed as Journal of Chemical Sciences in 2004. The journal publishes original research articles and rapid communications, covering all areas of chemical sciences. A significant feature of the journal is its special issues, brought out from time to time, devoted to conference symposia/proceedings in frontier areas of the subject, held not only in India but also in other countries.
