Lead halide perovskite nanocrystals have promising optoelectronic applications, with properties that can be tuned by changing synthesis conditions. A design of experiment approach was used to study eight factors in a screening study, focusing on five factors in a refined study. An empirical model was developed to understand the effects of these factors, allowing control over the photoluminescence peak position from 614 to 737 nm. This model provided greater insight into nanocrystal morphology and stability.
Lead halide perovskite nanocrystals have emerged as promising materials for optoelectronic applications. Their properties can be tuned by changing the synthesis conditions, but usually these conditions are studied in isolation rather than holistically. We report the use of design of experiment in the synthesis of MAPbI(3) nanocrystals. Eight factors were investigated in a broad screening study; we then focussed on five factors in a more refined screening study that targeted desired optoelectronic properties. An empirical model was developed and validated proving that five factors could be understood within a low number of experiments. By controlling the reactant solvent ratio, ligand concentration, ligand ratio, non-polar solvent polarizability, and purification solvent, the MAPbI(3) photoluminescence peak position could be tuned from 614 to 737 nm. The model has provided greater insight into the nanocrystal morphology and stability.
