首先使用石墨烯片作为模板与（B2 O3）-B-10反应来制备同位素（BN）-B-10片。BN片的边缘区域与其它区域相比具有高得多的氧掺杂比率。X射线激发的（BN）-B-10片层的光致发光光谱的发射峰由于同位素效应而变宽并发生红移。一个广泛的紫蓝色的发射在一个波长中心在类似于400 nm被分配到由于氧掺杂和BN网络中的缺陷的缺陷发射。
Isotopic (BN)-B-10 sheets were first prepared using graphene sheets as templates to react with (B2O3)-B-10. The edge-areas of BN sheets have much higher oxygen-doping ratios compared to other areas. The emission peak of X-ray excited optical luminescence spectra of the (BN)-B-10-sheets is broader and red-shifted because of the isotopic effect. A broad violet-blue emission at a wavelength centered at similar to 400 nm is assigned to the defect emission due to oxygen-doping and defects in the BN network.
