In Situ Transient Absorption Spectroscopy of Organometal Halide Perovskite Nanoparticles




Abstract: We use syringe filtration to rapidly sample a solvation-mediated synthesis of lead halide perovskite nanocrystals, enabling absorbance and fluorescence measurements during nanocrystal formation. The coupling of rapid sampling with a single-shot transient absorption technique will enable characterization of evolving excited state dynamics during nanocrystal nucleation and growth, aiding our ability to tune reaction parameters to achieve desired photophysics.
