Abstract:
Synthesizing perovskite nanostructures at room temperature via ligand-assisted reprecipitation method allows precise control of their shape and size. Additionally, doping with specific ions enables the production of additional photoluminescence bands, thereby providing opportunities for tuning their optical properties. Methods for the synthesis of organic-inorganic perovskite nanostructures with different morphologies at room temperature are presented. By selecting the type and ratio of ligands, perovskite nanocrystals and nanoplates with the chemical formula FAPbBr$_3$ were synthesized. Postsynthetic treating pre-synthesized perovskite nanocrystals with the MnCl$_2$ precursor at room temperature enabled the production of Mn$^{2+}$:FAPbCl$_x$Br$_{3-x}$ nanocrystals with emission in two
different spectral ranges.
