论文摘要
我们报告了在植入和随后的热退火后，高纯度钻石底物的发光特性的创建和表征。它们的室温光致发光发射由558 nm处的弱发射线组成，并在600-750 nm的光谱范围内具有强烈的带。在液体温度下的表征揭示了在600-670 nm光谱范围内的结构化线的存在。我们讨论了F相关光学中心对不同实验参数（例如工作温度和激发波长）的发射特性的依赖性。发射强度与F植入通量的相关性，以及在F植入和退火样品中对上述光谱特征的独家观察提供了强烈的指示，表明观察到的发射特征与钻石晶格中稳定的F含有F含有F的F含有F含有F含有F的F含有f含有F的有障碍。
We report on the creation and characterization of the luminescence properties of high-purity diamond substrates upon F ion implantation and subsequent thermal annealing. Their room-temperature photoluminescence emission consists of a weak emission line at 558 nm and of intense bands in the 600 - 750 nm spectral range. Characterization at liquid He temperature reveals the presence of a structured set of lines in the 600 - 670 nm spectral range. We discuss the dependence of the emission properties of F-related optical centers on different experimental parameters such as the operating temperature and the excitation wavelength. The correlation of the emission intensity with F implantation fluence, and the exclusive observation of the afore-mentioned spectral features in F-implanted and annealed samples provides a strong indication that the observed emission features are related to a stable F-containing defective complex in the diamond lattice.
