Monolayered boron nitride (BN) quantum dots (QDs; lateral size ≈10 nm) are fabricated using a novel method. Unlike monolayered BN sheets, these BN QDs exhibit blue-green luminescence due to defects formed during preparation. This optical behavior adds significant functionality to a material that is already receiving much attention. It is further shown that the QDs are nontoxic to biological cells and well suited to bio-imaging.
采用一种新方法制备了单层氮化硼（BN）量子点（QD；横向尺寸约为 10nm）。与单层 BN 片不同，这些 BN QD 由于在制备过程中形成的缺陷而呈现蓝绿色发光。这种光学行为为一种已经受到广泛关注的材料增添了重要的功能。进一步表明，QD 对生物细胞无毒，非常适合用于生物成像。
