Abstract Perovskite materials have attracted tremendous attention because of its high solar energy conversion efficiency. Recently, binary and ternary perovskite phases have been studied to control band-gap energy in the full visible range. It is still a challenging study to prepare homogeneous phased perovskite materials. Hence, there is increasing needs on the precise characterization of spectroscopic information. Here, we used photoluminescence lifetime imaging (PLIM) spectroscopy for studying the carrier dynamics and photo-stability of binary perovskite materials. The PLIM technique precisely evaluates the carrier dynamics of pure and phase segregated materials by emission spectrum and lifetime at a nanoscopic area.
