Halide perovskites are a promising class of materials for applications in energy storage and optics. These materials form across a wide range of compositions and crystal structures, and the resulting phases exhibit diverse properties. It is therefore important to be able to selectively target a desired halide perovskite phase. Synthetic control in these systems can be challenging, however, and pathways for achieving phase-selective synthesis are highly desirable. Here, we show that coprecipitation from organic solutions of long chain surfactants can be used to selectively synthesize three distinct phases in the Cs-Cd-Cl system: Cs2CdCl4, Cs3Cd2Cl7, and CsCdCl3. This presentation will describe the synthesis, characterization, and chemical reactivity of these three layered Ruddlesden-Popper phases that are of interest for non-linear optics.
