Manganese bromide (MnBr2) is a promising candidate in the syntheses of organic-inorganic hybrid compounds, especially the methyl lead bromide perovskites, with applications in the luminescence, lasing and solarcell [1]. Irradiation resistance of MnBr2 is a critical material property utilized in its industrial applications. Materials under the irradiation of high-energy particles, including electrons, ions and neutrons, will lead to bond instability, forming defects and changing structures. Consequently materials’ properties tend to deteriorate. On the other hand, particle irradiation sometimes results in certain in situ chemical transformations caused by the damage process [2]. Here we report a series of chemical evolutions of MnBr2 with Cu grid under the electron beam irradiation by in situ TEM [3].
