Crystalline borophene quantum dots and their derivative boron nanospheres

Abstract

Crystalline borophene quantum dots with two-photo fluorescence and their derivative boron nanospheres with hydrazine hydrate-dependent photoluminescence properties were prepared by an efficient high-power sonication method combined with chemical exfoliation and a one-step chemical coupling strategy, respectively. This work would extend the practical lighting applications of B-rich nanomaterials.
