- •
We report a single-step, facile and scalable synthesis route to fabricate BNQDs.
- •
Top-down approach employing high intensity sonication for the formation of BNQDs.
- •
The sonication implying exfoliation and etching of BNNSs in H3PO4 liquid medium.
- •
The thick BNNSs transform into thin BNNSs and these thin BNNSs breaks into BNQDs.
