Abstract
Synthesis of ultra-small and colloidal stable CsPbBr3 NCs with high PLQY and significant lifetime is a challenge indeed. In this study we have synthesized CsPbBr3 materials (TBIA-CsPbBr3, DBIA-CsPbBr3, DBHT-CsPbBr3, and NBS-CsPbBr3) obtained via hot injection methods employing TBIA (tribromoisocyanuric acid), DBIA (dibromoisocyanuric acid), DBHT (1,3-dibromo-5,5-dimethylhydantoin), NBS (N-bromosuccinamide) as the external bromine precursors. The TBIA-CsPbBr3 is found to have the smallest dimension (ultra-small ~5.6 nm) among these four. The outstanding traits exhibited by these NCs highlight their immense potential for practical applications across diverse fields.
