Abstract:The size modulation of perovskite nanocrystals is a well-established practice in existing literature, achieved through adjustments in reaction temperature or ligand chain lengths. However, our study introduces a novel approach, aiming to govern the dimensions (including shape, size, and phase) of these nanocrystals by manipulating the counter anions of Pb(II) during the synthesis by hot-injection method. We utilize diethyl 2-bromomalonate as the bromide precursor for this purpose. The resulting tunability is a… Show more
