| 摘 要： | 用B4C为硼源，利用CVD系统在N2-H2等离子体中合成了掺杂BNx纳米棒，接着在掺杂BNx纳米棒表面用CH4生长了石墨烯纳米片，制备出掺杂BNx-石墨烯三维纳米复合材料。一系列表征结果说明合成的纳米复合材料由C和O共掺杂的BNx纳米棒和石墨烯纳米片组成，其形成与碳氢基团的转换和掺杂BNx纳米棒的形变在石墨烯纳米片中产生的应力有关。室温发光性能表明石墨烯纳米片对掺杂BNx纳米棒的紫外光和绿光有明显的猝灭作用，起源于掺杂BNx-石墨烯界面上的电荷转移和电子散射。

| Abstract: | Three dimensional doped BNx-graphene hybrid nanomaterials were synthesized, where the doped BNx nanorods were synthesized in N2-H2 plasma by CVD, followed the growth of graphene nanoflakes on the surfaces of doped BNx nanorods in CH4 environment by CVD. The characterization results indicate that the synthesized hybrid nanomaterials are composed of C and O co-doped BNx nanorods and graphene nanoflakes. The formation of three dimensional C and O co-doped BNx-graphene hybrid nanomaterials is related to the conversion of hydrocarbon radicals and the stress in the graphene nanoflakes produced due to the deformation of doped BNx nanorods. The photoluminescence(PL) properties at room temperature indicate that ultraviolet and green light emitted from the doped BNx nanorods is quenched by the graphene nanoflakes, which results from the charge transfer and electron scattering occurring in the doped BNx-graphene interfaces. |
