Ligand-assisted re-precipitation (LARP) is one of the most practicing techniques for synthesizing colloidal nanocrystals (NCs). But due to its fast reaction kinetics, it offers limited synthesis control. In the present study, we report a novel, precursor silanization-based room temperature technique unveiling slow crystallization of CsPbBr/CsPbBr dual-phase nanocrystals (DPNCs) protected with a dense silica cloud-like matrix.
