首次提出了一种新的合成碳氮化硼(BC1.61N0.76)微纳米结构的方法，即在流动的氨气气氛中，将无定形硼粉、天然胶乳和三氯化铁(FeCl3)在1200 °C下进行热处理，合成了一种称为纳米片状修饰亚微丝的微纳米结构。微丝的直径约为200-500 nm，而纳米片的平均厚度不到20 nm。纳米薄片大多是以弯曲和皱折的形态分开的。这种微纳米结构在501.2和592.6 nm处表现出良好的可见光发射性能。提出了气-液-固(VLS)和气-固(VS)模型相结合的生长机制，形成了这种BC1.61N0.76微纳结构。
A novel route to the synthesis of boron carbonitride (BC1.61N0.76) micro-nano structures called nanosheet-decorated submicrowires is demonstrated for the first time, by annealing amorphous boron powder, natural rubber latex and ferric chloride (FeCl3) at 1200 °C in flowing ammonia atmosphere. The microwires have diameters of about 200–500 nm, while the nanosheets have an average thickness of less than 20 nm. The nanosheets are mostly separated with a bending and crumpling morphology. This micro-nano structure shows good visible-light emission property at 501.2 and 592.6 nm. A combination growth mechanism of vapor-liquid-solid (VLS) and vapor-solid (VS) model is proposed to be responsible for the formation of this BC1.61N0.76micro-nano structure.
