Photophysics of single silicon vacancy centers in diamond: implications for single photon emission

Elke Neu, Mario Agio, Christoph Becher

摘要:

金刚石中的单硅空位色心最近显示出高亮度、窄带宽、室温单光子发射的能力。本工作建立了一个描述铱表面金刚石纳米晶体中单SiV中心的三能级布居动力学模型,包括强度依赖的去搁置过程。此外,我们调查的亮度和光稳定性的单中心,并发现最大单光子速率为6.2 Mcps的连续激发下。我们调查的荧光收集效率和估计的SiV中心的量子效率。

英文摘要:

Single silicon vacancy (SiV) color centers in diamond have recently shown the ability for high brightness, narrow bandwidth, room temperature single photon emission. This work develops a model describing the three level population dynamics of single SiV centers in diamond nanocrystals on iridium surfaces including an intensity dependent de-shelving process. Furthermore, we investigate the brightness and photostability of single centers and find maximum single photon rates of 6.2 Mcps under continuous excitation. We investigate the collection efficiency of the fluorescence and estimate quantum efficiencies of the SiV centers.
