The precursor compound of two types of ZnSe magic-sized clusters

Precursor compounds (PCs) link quantum dots (QDs) and magic-sized clusters (MSCs), which is pivotal in the conversion between QDs and MSCs. Here, for the first time, we report the transformation, synthesis, and composition of a type of ZnSe PCs. ZnSe PCs can be directly transformed to two different MSCs with the assistance of octylamine and acetic acid at room temperature. The two types of MSCs exhibit sharp absorption peaks at 299 and 328 nm...
