Abstract
A planar hybrid microcavity containing isolated diamond particles with embedded silicon-vacancy (Si-V) color centers in its active layer is fabricated by plasma-enhanced chemical vapor deposition. Distributed Bragg reflectors are produced on the basis of alternating quarter-wave a-Si1 − x C x :H and a-SiO2 layers. The color centers are controllably introduced from the gas phase during the course of growth of the diamond particles. A narrowing to 5 nm of the zero-phonon line at a wavelength of 738 nm and suppression of the phonon wing in the photoluminescence spectrum of the Si-V color centers are achieved.
