    “…We present in this work electronic structure ab-initio calculations based on multireference configuration interaction plus Davidson correction of three magnesium monohalides and their cations (MgCl, MgBr, MgI, MgCl(+), MgBr(+), and MgI(+)). We determine the spectroscopic constants T(e), R(e), ω(e), B(e), and α(e) and the dissociation energies D(e) for their bound states. …”

    “…Achieving good stability while maintaining excellent properties is one of the main challenges for enhancing the competitiveness of luminescent perovskite CsPbX(3) (X=Cl, Br, I) nanocrystals (NCs). Here, we propose a facile strategy to synthesize ceramic-like stable and highly luminescent CsPbBr(3) NCs by encapsulating them into silica derived from molecular sieve templates at high temperature (600–900 (o)C). …”

    “…Quantitatively, we find a reduced activation energy, a reduced diffusion coefficient, and a reduced concentration for halide ions in MAPbBr(3) compared to MAPbI(3). Understanding this difference in mobile ion migration is a crucial step in understanding the enhanced stability of MAPbBr(3) versus MAPbI(3).…”

    “…It was chosen due to the provisions of both a surrounding protective layer for inorganic perovskite and elastic, as well as healing ability to the whole organic-inorganic composite. This fabricated CsPbBr(3)/PBA-co-PNMA composite was demonstrated to stably persist against the suffering from hydrolysis of perovskites when exposed to a high moisture environment. …”
