Ultrafast charge transfer enhanced nonlinear optical properties of CH₃NH₃PbBr₃ perovskite quantum dots grown from graphene.

ABSTRACT: Halide perovskite quantum dots (PQDs) have exhibited significantly superior nonlinear optical properties compared to traditional semiconductor materials thanks to their peculiar physical and electronic structures. By further improving the nonlinear optical properties of PQDs, it is expected to adapt to ultrafast photonics applications. This work reported the nonlinear optical properties of methylammonium lead bromide-graphene (CH₃NH₃PbBr₃-G) composites synthesized by growing CH₃NH₃PbBr₃ quantum dots directly from a graphene oxide lattice. Our experiments indicate that the combined advantages of the ultrafast charge transport properties from graphene and the strong charge generation efficiency of perovskite can be integrated
