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.

首次证明了通过机械化学处理 PbBr ₂和用溴化铯分层的六方氮化硼的干混合物制备 CsPbBr _{3 /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 CsPbBr ₃纳米片。与机械化学合成的单个 CsPbBr ₃不同，CsPbBr ₃ /h-BN 纳米复合材料以亮绿色发光为特征。由于氮化硼的疏水导热层的存在，纳米复合材料增强了对空气湿气和阳光的抵抗力。
