Insight into the synthesis of colloidal cesium tin halide perovskite nanocrystals: size, shape control and phase transition.

Colloidal nanocrystals (NCs) of fully inorganic perovskites have attracted much attention for their wide optoelectronic applications. Cesium tin halide (CsSnX3, X= Cl, Br, I) NCs possess the advantage of environmental friendliness. While there have b…
