Stability study of organometal halide perovskite and its enhanced X-ray scintillation from the incorporation of anodic TiO₂ nanotubes.

ABSTRACT: Organometal halide perovskite-based optoelectronic devices are currently a hot research area owing to their unique properties, but widespread commercialization is plagued by their poor long-term stability. So far, the degradation mechanism of organometal halide perovskites is still indistinct due to limited real time systematic study. In this work, we in situ study the crystal evolution of an organometal halide perovskite CH₃NH₃PbI₃, which is prepared on different kinds of framework substrates. Based on the in situ grazing incidence X-ray diffraction and X-ray near absorption edge spectrum, we observe the formation of some 2D networks of [PbI₆]^4- octahedra intermediates during CH₃NH₃PbI₃ d
