Fiber optic sensors are widely used in environmental, biological and chemical sensing. Due to the demanding environmental conditions in which they can be used, there is a risk of damaging the sensor measurement head placed in the measuring field. Sensors using nanolayers deposited upon the fiber structure are particularly vulnerable to damage. A thin film placed on the surface of the fiber end-face can be prone to mechanical damage or deteriorate due to unwanted chemical reactions with the surrounding agent. In this paper, we investigated a sensor structure formed with a Zinc Oxide (ZnO) coating, deposited by Atomic Layer Deposition (ALD) on the tip of a single-mode fiber. A nanocrystalline diamond sheet (NDS) attached over the ZnO is described. The diamond structure was synthesized in a Microwave Plasma Assisted Chemical Vapor Deposition System. The deposition processes of the nanomaterials, the procedure of attaching NDS to the fiber end-face covered with ZnO, and the results of optical measurements are presented.
光纤传感器广泛应用于环境、生物和化学传感领域。由于其使用环境条件苛刻，放置在测量区域的传感器测量头存在损坏风险。使用沉积在光纤结构上的纳米层的传感器尤其容易受损。置于光纤端面表面的薄膜可能易于受到机械损伤，或者由于与周围介质发生不必要的化学反应而变质。在本文中，我们研究了一种传感器结构，该结构由通过原子层沉积（ALD）沉积在单模光纤尖端的氧化锌（ZnO）涂层形成。描述了附着在ZnO上的纳米晶金刚石片（NDS）。金刚石结构是在微波等离子体辅助化学气相沉积系统中合成的。介绍了纳米材料的沉积过程、将NDS附着到覆盖有ZnO的光纤端面的过程以及光学测量结果。
