Two-dimensional (2D) CsPbBr nanoplatelets (NPLs) have attracted great attention as one of promising semiconductor nanomaterials due to their large exciton binding energy and narrow emission spectra. However, the labile ionic and weakly bound surfaces of deep-blue emitting CsPbBr NPLs with wide bandgap result in their colloidal instability, thus degrading their optical properties. It is challenging to obtain deep-blue emitting CsPbBr NPLs with excellent optical properties.

CdTe MSCs are usually synthesized by direct synthesis, a method that must avoid the formation of quantum dots by selecting suitable active precursors and precisely controlling the reaction temperature. In addition, the organic Cd compounds and superhydrogenated precursors used are air-sensitive.

- Magic-size clusters (MSCs) are unique molecular materials that sit at the intersection of small molecules and solids, offering key insights into how nanocrystals form.
- The synthesis of alloy ZnCdSe MSCs was successfully achieved for the first time using cation exchange in a diamine solution at room temperature, resulting in a sharp absorption peak at 352 nm.
- The study highlights the importance of diamines for stabilizing the MSCs and demonstrates how factors like reaction temperature and diamine concentration impact the synthesis of these alloy MSCs.
