摘要:

我们报告的系统表征的光学性质的金刚石色心的基础上的铅杂质。在405-520 nm范围内的不同激发波长和4-300 K范围内的不同温度下,对它们的光谱发射进行了系综光致发光分析。一系列观察到的光谱特征包括与Pb相关的缺陷相关的不同发射线。最后,室温下的单光子发射器的490.5 nm激光激发下的调查报告,揭示不同的光谱特征与那些已经报道的514 nm激发下。这项工作相对于以前对Pb相关色心的研究取得了实质性进展,无论是在一系列清晰的光谱特征的归属方面,还是在对这种缺陷形成过程的理解方面,都表明了该系统在量子技术中高影响力应用的潜力。

英文摘要:

We report on the systematic characterization of the optical properties of diamond color centers based on Pb impurities. An ensemble photoluminescence analysis of their spectral emission was performed at different excitation wavelengths in the 405-520 nm range and at different temperatures in the 4-300 K range. The series of observed spectral features consist of different emission lines associated with Pb-related defects. Finally, a room-temperature investigation of single-photon emitters under 490.5 nm laser excitation is reported, revealing different spectral signatures with respect to those already reported under 514 nm excitation. This work represents a substantial progress with respect to previous studies on Pb-related color centers, both in the attribution of an articulated series of spectral features and in the understanding of the formation process of this type of defect, thus clarifying the potential of this system for high-impact applications in quantum technologies.
