Congratulations to ex-group members Barry McKenna and Abhinav Shivkumar, and current group member Bethan Charles for their new paper, which has just been published in Nanoscale.
The stability and reproducibility of perovskite nanocrystals (PNC) produced by ligand-assisted reprecipitation (LARP) is investigated. Significant differences in optical properties and morphology are observed depending on specific synthetic factors. These differences can have profound effects on the resulting emission and stability of PNCs, although this is rarely reported in the literature. However, this information is important for new researchers entering a competitive field as well as in the drive to develop realistic pathways to scale-up synthesis. Therefore, we systematically examine (1) the effect of dilution of the parent dispersion, (2) choice of the halide source and ratio and (3) choice of capping ligand concentration in PNC synthesis.
