The possibility of increasing the spontaneous emission rate for silicon-vacancy (SiV) centers in nanodiamonds placed in a Fabry-Perot microcavity was studied. For this purpose, a plano-concave open access microcavity was designed. The cavity was tested using diamond nanocrystallites, placed on a flat mirror. Nanodiamonds were synthesized from adamantane and Si-containing adamantane derivative by high pressure, high temperature (HPHT) technique. The controlled room temperature cavity coupling gives rise to a resonant Purcell enhancement of the SiV zero-phonon line by a factor 1.4.
