六方氮化硼纳米片具有许多独特的性质，在电子器件和深紫外发光材料等方面有着广泛的应用前景。本文报道了一种制备少层大尺寸BNNSs的化学剥离法。通过相关仪器表征，我们证明这种制备方法可以成功地从块状BN粉末中剥离出BNNS。从化学发光光谱可以看出，所制备的BNNSs比BN粉末具有更强的化学发光能力。在实验结果分析的基础上，提出了剥离机理，并通过SEM原位检测进行了验证。
Owning many peculiar properties, hexagonal boron nitride nanosheets (BNNSs) have lots of potential applications, such as electronic devices and deep ultraviolet emitters. In this article, a chemical exfoliation method to prepare few-layer and large size BNNSs is reported. Through related instrument characterizations, we demonstrated that this preparation method can allow the exfoliation of BNNSs from bulk BN powder successfully. From CL spectra, the as-prepared BNNSs were proved to show stronger CL emission ability than BN powder. Based on the experiment results analysis, we proposed an exfoliation mechanism and verified it through in situ SEM detection.
