Boron nitride (BN) has encouraged researchers to use it in composite materials due to its different properties. BN-based nanocomposites have been synthesized using a modified chemical method. X-ray diffraction (XRD) results confirmed the formation of hexagonal-BN and nickel oxide (NiO) phases in samples. XRD analysis shows that samples are textured along (100) plane which distorts structure and leads to formation of defect states. The electron density difference between BN and NiO as well as textural growth are two main reasons for variation in diffraction peak intensities. Raman spectroscopic results also revealed that peak intensity and position shifts with increase in NiO content, due to the distortions induced by NiO incorporation confirming the presence of defect states. Field emission scanning electron microscopy (FESEM) results showed that morphology of synthesized nanocomposites varies with increase of NiO concentration. Ultra-violet (UV)-visible results revealed that the absorption edge is red-shifted with NiO content, consequently, the band-gap energy of composites get decreased. Distorted crystal structure and defect states are responsible for variation in structural, morphological as well as optical properties. Results suggested that the nanocomposites can be explored for photodetection as well as gas sensing applications.

氮化硼（BN）由于其不同的特性而鼓励研究人员在复合材料中使用它。使用改良的化学方法合成了基于B​​N的纳米复合材料。X射线衍射（XRD）结果证实了样品中形成了六方晶BN和氧化镍（NiO）相。XRD分析表明，样品沿（100）平面织构化，从而扭曲了结构并导致形成缺陷状态。BN和NiO之间的电子密度差以及组织生长是衍射峰强度变化的两个主要原因。拉曼光谱结果还表明，由于NiO掺入引起的畸变，证实了缺陷状态的存在，峰强度和位置随NiO含量的增加而移动。场发射扫描电子显微镜（FESEM）结果表明，合成的纳米复合材料的形貌随NiO浓度的增加而变化。紫外线（UV）可见的结果表明，吸收边缘随NiO含量的变化而发生红移，因此，复合材料的带隙能量降低。变形的晶体结构和缺陷状态是导致结构，形态以及光学性能变化的原因。结果表明，纳米复合材料可用于光检测和气体传感应用。变形的晶体结构和缺陷状态是导致结构，形态以及光学性能变化的原因。结果表明，纳米复合材料可用于光检测和气体传感应用。变形的晶体结构和缺陷状态是导致结构，形态以及光学性能变化的原因。结果表明，纳米复合材料可用于光检测和气体传感应用。
