Self-assembled halide perovskite quantum dots in polymer thin films showing temperature-controlled exciton recombination.

ABSTRACT

Rationally assembled supramolecular structures of organic chromophores or semiconductor nanomaterials show excitonic properties different from individual molecules or nanoparticles. We report polymer-assisted assembly formation and thermal modulation of excitonic recombination in self-assembled formamidinium lead bromide perovskite quantum dots.
