摘要：
We report the narrow inhomogeneous distribution of the zero-phonon line from tin-vacancy (Sn-V) centers in diamond and the overlap of spectra from multiple separated Sn-V centers. Photoluminescence excitation spectroscopy measurements at a cryogenic temperature show that Sn-V centers 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 Sn-isotope-dependent resonant frequencies. Owing to the narrow inhomogeneous distribution, we observe multiple Sn-V centers showing almost identical photon frequencies and linewidths. Identical Sn-V centers are also observed between two diamond samples, confirming the reliable fabrication of high-quality Sn-V centers.
