摘要

首次证明了将PbBr2和六方氮化硼与溴化铯分层的干燥混合物进行机械化学处理制备CsPbBr3/h-BN纳米复合材料的可能性。x射线衍射和电子显微镜研究表明，使用这种方法可以形成结晶的CsPbBr3纳米片。与机械化学合成的单个CsPbBr3不同，CsPbBr3/h-BN纳米复合材料具有亮绿色发光的特征。由于氮化硼疏水导热层的存在，纳米复合材料增强了对空气湿度和阳光的抵抗力。

Structure and Optical Properties of Mechanochemically Obtained Nanocomposite CsPbBr3/h-BN

For the first time, the possibility of a CsPbBr₃/h-BN nanocomposite preparing by a mechanochemical treatment of a dry mixture of PbBr₂ and a hexagonal boron nitride delaminated with cesium bromide has been demonstrated. X-ray diffraction and electron microscopy studies show that the use of this method leads to the formation of crystalline CsPbBr₃ nanosheets. Unlike to the mechanochemically synthesized individual CsPbBr₃, the CsPbBr₃/h-BN nanocomposite is characterized by bright green luminescence. The nanocomposite has enhanced resistance to air moisture and sunlight due to the presence of a hydrophobic thermally conductive layers of boron nitride.
