A novel, simple, and low-cost in situ surface vitrification method has been effectively developed to enhance the optical transparency of rough surface sapphire at UV–visible–IR regions. This method is to obtain a glass layer on the sapphire surface through vitrifaction process. The thickness, refractive index, components and transition temperature of the glass layer have been investigated and discussed respectively by XRD, DSC, SEM and EDS elemental analysis. The experimental results show that the vitrified sapphire has high transparency even after 1000 °C annealing at UV–visible-IR regions.

通过表面振动处理提高了粗糙表面蓝宝石的透明度

已经有效开发了一种新颖,简单且低成本的原位表面玻璃化方法,以增强粗糙表面蓝宝石在UV-可见-IR区域的光学透明性。该方法是通过玻璃化工艺在蓝宝石表面上获得玻璃层。通过XRD,DSC,SEM和EDS元素分析分别研究和讨论了玻璃层的厚度,折射率,组分和转变温度。实验结果表明,即使在紫外-可见-红外区域进行1000°C退火后,玻璃化的蓝宝石也具有很高的透明度。
