Fluorescence recovery and fluorescence correlation microscopy studies of colloidal perovskite diffusivity
Year: 2026
Type: conference-paper
Abstract: We employed two luminescence microscopy techniques to determine the diffusivity of perovskite nanocrystals in colloidal solutions crucial for holographic recording of diffraction-luminescent elements using photoinduced diffusion. Despite the dramatic differences in the two approaches based on luminescence photobleaching-recovery and fluctuation statistics, they yielded consistent results indicating the diffusion of nanocrystals ensemble with apparent hydrodynamic diameters within the 10 to 25 nm range. The diversity of sizes manifests itself in bleaching experiments via peculiar shape of luminescence profiles and dynamics of their diffusion-conceived broadening.
