本文报道了金刚石中锡空位（-V）心零声子谱线的窄的非均匀分布和多个分离的-V心谱线的重叠。在低温下的光致发光激发光谱测量表明，-Vcenters表现出稳定的荧光和线宽接近傅里叶变换的限制线宽。的不均匀分布是低至约4 GHz，这使得观测的同位素依赖的共振频率。由于窄的不均匀分布，我们观察到多个V中心，显示几乎相同的光子频率和线宽。在两个金刚石样品之间也观察到相同的V心，证实了高质量V心的可靠制造。
We report the narrow inhomogeneous distribution of the zero-phonon line from tin-vacancy (-V) centers in diamond and the overlap of spectra from multiple separated-Vcenters. Photoluminescence excitation spectroscopy measurements at a cryogenic temperature show that-Vcenters exhibit stable fluorescence and linewidths close to the Fourier-transform-limited linewidth. The inhomogeneous distribution is as low as about 4 GHz, which enables the observation of-isotope-dependent resonant frequencies. Owing to the narrow inhomogeneous distribution, we observe multiple-Vcenters showing almost identical photon frequencies and linewidths. Identical-Vcenters are also observed between two diamond samples, confirming the reliable fabrication of high-quality-Vcenters.
