The direct coating of 2D hexagonal boron nitride (h‐BN) on insulating solid glass will endow glass with advanced properties, thus offering killer applications of the new type hybrid of h‐BN glass. However, daunting challenges still remain regarding the direct growth methodology of h‐BN on glass. Herein, a catalyst‐free chemical vapor deposition route for the direct synthesis of 5 in. uniform h‐BN thin films on functional quartz and sapphire glass is developed. The optical transparency, surface wetting, and thermal conductivity of glass are readily tailored by varying the deposited h‐BN thicknesses from monolayer to over 20 layers. Encouragingly, the as‐obtained h‐BN/sapphire glass can serve as a stress‐releasing substrate for the van‐der‐Waals epitaxial growth of AlN functional layers, as well as a thermal conductive template for constructing high‐performance deep‐ultraviolet light‐emitting diodes. This work hereby provides a brand new direction for the application of h‐BN glass in next‐generation solid‐state lighting devices.

在玻璃上直接生长5英寸均匀六方氮化硼，用于高性能深紫外发光二极管

在绝缘固体玻璃上直接涂覆2D六方六方氮化硼（h-BN）将使玻璃具有先进的性能，从而为新型h-BN玻璃混合物提供了杀手级的应用。但是，玻璃上h-BN的直接生长方法仍然面临严峻的挑战。本文中，开发了一种无催化剂的化学气相沉积路线，可在功能石英和蓝宝石玻璃上直接合成5英寸均匀的h-BN薄膜。通过将沉积的h-BN厚度从单层更改为20层以上，可以轻松调整玻璃的光学透明度，表面润湿性和热导率。令人鼓舞的是，如此获得的h-BN /蓝宝石玻璃可以用作AlN功能层的范德华外延生长的应力释放基体，以及用于构建高性能深紫外发光二极管的导热模板。因此，这项工作为h-BN玻璃在下一代固态照明设备中的应用提供了全新的方向。
