For the realization of quantum networks, single-photon emitters with excellent optical and spin properties are essential. One of the promising candidates is lead-vacancy (PbV) centers in diamond. In this study, we fabricated Solid-Immersion-Lens (SIL) containing PbV centers to enhance fluorescence collection efficiency. Optical measurements revealed a fluorescence intensity several times higher than that reported in the previous study without SIL, demonstrating, for the first time, a significant enhancement in fluorescence. This result represents a meaningful step toward the realization of quantum networks.
