Nonlinear optical responses of all-inorganic lead halide perovskite nanostructures by time-resolved beam-deflection technique

Samrat Roy, Arnab Mandal, Akshay Raj R. +2

We have investigated nonlinear refraction in all-inorganic halide perovskites, the CsPbBr${}_3$ and CsPbBr${}_{1.5}$I${}_{1.5}$ nanosheet and quantum dot colloids in toluene, by a novel…
