Abstract
本发明提供一种氧化钇保护下的高性能氮空位色心金刚石材料及其制备方法和应用，属于量子材料技术领域。本发明中先对金刚石衬底进行电子辐照和清洁，接着采用氮等离子体进行处理，然后沉积氧化钇涂层，将沉积有氧化钇涂层的金刚石衬底在真空条件下退火，得到了高性能氮空位色心金刚石材料。本发明中通过氮等离子体对金刚石进行处理，能够增加金刚石中的替位氮浓度，使得在后续的退火处理过程中能提升NV‑色心浓度；同时，在金刚石衬底上沉积氧化钇涂层，能减少金刚石表面缺陷的产生，提升NV‑色心浓度，使得制备得到的金刚石材料具备优良的抗腐蚀性能。通过本发明中的制备方法制备得到的金刚石材料能够用于制备在极端条件下使用的量子传感器。
