Simultaneous Dynamic Light Scattering, Absorbance and Photoluminescence Measurements of Colloidal Nanoparticles. Application to Colloidal Stability and Aggregation Kinetics of CsPbBr₃ Nanocrystals.

ABSTRACT: An original but simple instrument is developed, capable of performing simultaneous Dynamic Light Scattering (DLS), Absorbance (ABS), and Photoluminescence (PL) measurements on suspensions of colloidal nanoparticles. The instrument is designed as a standard laboratory tool that, by using only commercial components, enables rapid analysis of the sample under investigation. The setup offers two significant benefits: first, it allows for the simultaneous analysis of the very same sample, overcoming limitations arising from the measurements being performed on distinct specimens, under diverse experimental settings, at different times; second, it enables to monitor the kinetic evolution of nanocrystals (Ncs) colloidal stability in time, with a time resolution of ≈ 100 s, which is considerably sh
