Cs-based lead perovskites nanocrystals (CsPbX3) will be synthesized in situ in a x-ray beam line from synchrotron source to evaluate their growth from the precursors. The precursors will be dissolved in a vessel and heated. The growth of the nanocrystals will be probed via SAXS and WAXS. The purpose is to elucidate the growth mechanism of these nanocrystals, a pioneer work in the literature.
