摘要:

我们报告的创建和高纯度的金刚石基板的荧光特性的F离子注入和随后的热退火的表征。它们的室温光致发光发射由558 nm处的弱发射线和600 - 750 nm光谱范围内的强带组成。在液态He温度下的表征揭示了在600 - 670 nm光谱范围内存在一组结构化的谱线。我们讨论了不同的实验参数,如工作温度和激发波长的F相关的光学中心的发射特性的依赖关系。的相关性的发射强度与F注入的注量,和独家观察上述光谱特征的F-注入和退火的样品提供了一个强有力的指示,所观察到的发射功能相关的稳定的含F缺陷的复杂的金刚石晶格。

英文摘要:

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.
