Study of the local optical properties using electron beam (e-beam) canprovide a valuable information concerning the inspection of the materialsquality, the presence of the different phase inclusions and defects. Halideperovskites have been shown to be highly sensitive to external stressconditions like ambient atmosphere, light, and heat. In this paper, thecathodoluminescence (CL) spectroscopy has been exploited to carry out theinvestigation of CH3NH3PbBr3 monocrystals under low energy electron beamirradiation. The CL spectra exhibited strong transformation with the increaseof the irradiation dose and significant shifts of the peak maximums from 2.23eV to >2.5 eV. Utilizing a larger e-beam energy (>20 keV) was found to bepreferable to slow down the dynamics of the decomposition and corrosion. Themechanisms of the changes in MAPbBr3 properties after e-beam exposure andcorrelation to the in-depth distribution of deposited energy were discussed.
